ah well, I may be wrong above, just read it somewhere on a youtube video compaison. I have an Xbox 360 and I see they had trouble fitting Assassin's Creed to the dual layer 10< gigabyte DVD, but had no trouble putting it on BlueRay for PS3, - the ONLY time I have actually been proved usefullness of the extra and usually wasted space on a BR Disc.
Iy may be a little wasted at the minute but with games becoming bigger the extra space is going to be needed - why should game developers be held back by the limits of an 'old' (I use that term loosely) format when there's new formats available for the space needed? I know having to choose between two formats is a tough one for the developers so can understand why they're sticking with the common format at the minute (DVD)
Just a quick update. I found this in my CompTIA A+ book: HD DVD can hold 15-18 GB of data on each layer. Blu Ray Disc can hold 25 GB of data on each layer. So Blu Ray disc has a higher capacity, resulting in more space to save files and movies with a higher quality because there's more space on the disc. But the quality is about the same as on a HD DVD, because otherwise a movie has to be re-encoded to be able to fit on the other disc format.
games will probably still fit fine on a dual layer DVD for another 2 years at least I think. The game developpers are surprisingly good at compressing the game content
Despite my preference for one format, I still don't want one format to win over another which results in poor quality for the consumer. Warner have switched to blu-ray, but I wouldn't say it's quite over yet. Universal and Paramount are still big studios in my mind, but I don't know all that much about studios.
Well obviously HD has lost out in the battle. I am not sure there is much else to say in this. I hope you get a blue-ray. The quality is much better in my opinion too.
