Supposedly they are going to replace DVD players, VCR and drives on computers in the next few years. I don't think any blu-ray recorders are on sale in the United States yet. From blu-ray.com:
Blu-ray , also known as Blu-ray Disc (BD) is the name of a next generation optical disc format jointly developed by the Blu-ray Disc Association (BDA), a group of leading consumer electronics and PC companies ( including Apple, Dell, Hitachi, HP, JVC, LG, Mitsubishi, Panasonic, Pioneer, Phillips, Samsung, Sharp, Sony TDK and Thompson). The format was developed to enable recording, rewriting and playback of high0definition video (HD, as well as storing large amounts of data. A single layer Blu-ray Disc can hold 25GB, which can be used to record over 2 hours of HDTV or more than 13 hours of standard-definition TV. There are also dual-layer versions of the discs that can hold 50GB.
While current optical disc technologies such as DVD, DVD-R, DvDrW, and DVD-RAM use a red laser to read and write data, the new format uses a blue-violet laser instead, hence the name Blu-ray. Despite the different type of lasers used, Blu-ray products can easily be made backwards compatible through the use of a BD/DVD/CD compatible optical pick-up and allow playback of CDs and DVDs. The benefit of using a blue-violet laser (405nm)is that it has a shorter wavelength than a red laser(650nm), which makes it possible to focus the laser spot with even greater precision. This allows data to be packed more tightly and stored in less space, so it's possible to fit more data on the disc even though it's the same size as a CD/DVD. This together with the change of numerical aperture to 0.85 is what enables Blu-ray Disc to hold 25GB/50GB.
With the rapid growth of HDTV, the consumer demand for recording HD programming is quickly rising. Blu-ray was designed with this application in mind and supports direct recording of the MPEG-2 TS (Transport Stream) used by digital broadcast, which makes it highly compatible with globals standards for digital TV. This means that HDTV broadcasts can be recorded directly to the disc without any qualaity loss or extra processing. To handle the increased amount of data required for HD, Blu-ray employs a 36Mbps data transfer rate, which is more than enough to record and playback HDTV while maintaining the original picture quality. In addition, by fully utilizing and optical disc's random accessing features, it's possible to playback video on a disc while simutaneously recording HD video.
Blu-ray is expected to replace VCRs and DVD recorders over the coming years, with the transition to HDTV. The format is also likely to become a standard for PC data storage and HD movies in the future.

Good luck replacing DVDs. It seems too soon to do that, but who knows? DVDs could be destined to become the next 8-track and this the next video casette.

I have and don't hold your breath just yet. Blu-ray is one of four competeing formats for the next generation of high capacity non-magnetic disc storage systems (CD/DVD). The other three Formats are Blue-Laser and HD-DVD and EVD.
Each format has pro's and cons. Blu-ray is the most promissing, for it offers the ability to store around 27 GB on a single disc using a blue-violet laser on a single sided, single layer disc. This makes this format ideal for recording HDTV video format and very high end security features. However using it will mean large investment in new manufacturing facilities, and that you will probably have to get rid of all your current red-laser driven players.
Blue laser is similar but it can storage 15GB on a single layer DVD. It also allows ofr much less investment in manufacturing facilities as well as claiming the ability of being able to playback existing red-laser formats. However this format is only supported by two companies.
HD DVD is a high compression format that allows for up to 4.7 GB of data on a single layer CD, but still requires slightly modified equipment to read it. Very little investment needed in order to produce.
Lastly, EVD is a new data compression format that uses existing red-laser technology, allowing you to squeeze 4.7 GB of data onto an existing disc. The pro's are that no new investment in manufacturing recording or playback technology is needed. Cons - Only favored by Chinese manufacturers.
The bigest backing by the most companies and studios is being given to blu-ray at this point, and it is widely expected to become the industry standard going forward.

Did any one saw Blu ray players in real life??? I did!!!
It was from Sydney Home Show few days ago at Darling Harbour (same place as sydney motor show here). The LG one looks nice which is the normal blu-ray player and the Samsung one is Blu-ray recorder.
Santeno, i think Blu-ray will win this format wars because it would be good on tv shows but not one movie. I guess more movies, TV's and games studios is with blu-ray format than HD-DVD for now.

PS3 is coming with Blu-ray reader , isn't it?

[Arratherimi]

Yep, that's what i said games studios including sony, konami, ea etc.
Microsoft is similar with HD-DVD drive for Xbox 360.
LG would get Blu-ray/HD-DVD combo player according to
engadget.com.

True, but all that is dependednt on how quickly and cheaply can super high capacity, solid state storage media develops (which is already approcahing the capacity of the bigger consumer hard drives - but is not commercially viable). If you can store similar capacity in solid state mdeia for the same money as blue Ray, then the prefered technology would be solid state. Smaller packaging, no new hardware necessary, can play on existing machines, much more resistant to damage (no moving parts).

adult-entertainment industries have backed blu-ray
Sony did better in this format war than w/ SACD by rallying more companies to their cause.

I hope Sony wins.
Besides, PS3 games are going to be BD-based, while the X360's HD-DVD drive is external and, thus, probably not for games.

i do too

dont worry it aint, 360 is dvd-9 only, the hd drive is fr movies and money...

if thats the case sony has finally won something... (they also backed UMD's in japan
the dvd is almost dead(it still have some usage in audio and data storage)
Blu Ray is the future, i could save crazy sketchs on one of those.
