If the average PSX game was, lets say, 600 megs, and the average PS2 game was 3 gigs. Okay (though the average for both is probably a lot smaller). Five time increase. If it keeps up, then we're looking at 15 gig games, still well within the capacity of dual-layer HD-DVD. Blu-Ray may be a bit excessive, at least for this generation.
