The whole two formats thing just pisses me off. +R and -R, Blue Ray and HD-DVD and SACD and DVD-Audio. Dear lord, pick a f*cking format and work together!
blu ray seemed to be winning on about all counts last i was reading up on it. plus, it seems to be bluray having all the newsstuff about disks made of corn or whatever, which perhaps indicates there's a lot more research going into the 'third party' type of stuff - where the researchers are placing their bets.

Both are backwards compatible with dvds, which is a must for consumers. In that case, I do believe blu-ray will win, but I like the sound od hd dvd alot better. People are already used to hearing and saying HDTV, so HD-DVD sounds much more appropriate than blu-ray.

yea hd dvd is aiming low. they want my money? u better make a decent tech leap to justify it. more space = more options. now with wmv and other formats being allowed on blueray theres no point in hd dvd. u need options. already our dvds are bitrate starved when filled with features or multi-angle features for alternate versions(beauty and the beast a good example).
here's the bit on tdk's antiscratch coating http://www.newscientist.com/news/news.jsp?id=ns99996583
Super-tough coating for cellphones and discs

The colour LCD screens on cellphones and PDAs can get badly scratched in pockets stuffed with loose change and keys. And CDs and DVDs become unplayable in no time when children use them as indoor frisbees. Now a tough, transparent polymer coating developed by chemists in Japan is set to make scratched phone screens and scuffed discs a thing of the past.
In one of the most convincing technology demonstrations this reporter has witnessed, I was handed a CD, a wire-wool pan scourer and some permanent marker pens, and invited to scratch or mark the discs. Hard as I tried, I could not make a single mark on the disc with the scourer. And the ink simply wiped off.
The only person to have succeeded in damaging the disc had undertaken a determined attack with a Swiss army knife, according to TDK, the company that has developed the coating.
Two years ago TDK, a maker of tape and disc-based recording media, began developing what was initially a single-layer coating to make DVDs more resistant to scuffing. But the new coating is far tougher, and it is transparent to the full spectrum of visible light rather than just a DVD?s red laser, so it can also be used to protect the plastic surface of colour liquid crystal displays (LCDs).
Layered approach
Two separate layers of fine silica particles prevent scratches, and fluorine-containing resins in each layer repel ink marks. To deposit the first layer of the new coating, a mix of silica microparticles 50 micrometres across and a solution of a fluorine-containing resin are spread on by spin-coating the surface at 8000 rpm.
After they have dried a second layer, made from a mix of another fluorine-containing resin and a curing agent called acetophenone, is spread on top and cured by shining ultraviolet light onto it. Quite how the two layers work together has not been revealed, as TDK is reluctant to reveal any more detail than its newly filed patents contain.

The tough silica particles resist abrasion. Meanwhile, the fluorine-rich resins do not absorb water, so the ink forms droplets that can be wiped off. On a CD or DVD, any residual droplets are much smaller than the laser spot used to read the disc, and so cause no data loss during playback.
The new coating has also provided a boost to the upcoming high-capacity Blu-ray recording discs that Sony, Philips and Panasonic plan to launch next year as a successor to DVDs. The coating will do away with the need for any awkward cassette-style ?caddy? mechanism to protect the discs.
The consortium is pleased because no consumer optical disc that uses a caddy has ever been a commercial success. For instance, the computer industry quickly stopped using caddies for CD-ROMs in the 1990s, and Commodore?s CDTV games system ? launched in 1991 ? was a complete flop.
TDK is not alone in developing a tough coating for hand-held gadgets. The Japanese-European joint cellphone venture Sony Ericsson this month launches its P910 internet-capable smartphone. The gadget sports an ultra-hard scratch-resistant screen that uses a hardening technology it developed in-house. However, unlike TDK, Sony Ericsson is not planning to reveal any details on the recipe for its coating.

Blu-Ray has this one wrapped up 
Here's my older thread about it.
There's a few good links in there too.

fwiw there is a third format - New Medium Enterprises, Inc. announced today the Public Unveiling of its stunning 20 GB Red Laser, High-Definition Versatile MultiLayer Disc (VMD)
only 20gb, but it's significant plus is full backwards compatibillity with DVD. Neither HDDVD or Bluray have that, or so i thought, but both have come up with technologies for the drives to be able to also handle DVD disks.
