I think that Uncharted uses up to 2 gigs of HD to cache from the Blu-ray which is the ideal solution. I think the 3 ways that have been used so far to deal with the speed issue is caching to the HD (Uncharted), install to the hard drive (MGS4, DMC4, GTA4), write the data multiple times to different portions of the Blu-ray (Oblivion).
12x DVD speed issues are overcome by writing the game data to the outer portion of the dvd. Aren't all 360 games writtin on dual layer dvd's? If so this drops the speed to the equivalant of an 8x dvd. The PS3 can play dvds at the speed of an 8x drive as well. I don't know if there is any technical reason why PS3 games can't be on dvds, other than the fact that Sony makes money on blu-ray production.
Thanks for the input, Jeff.
