So are we in agreement that "IF" a game would require 50GB for next gen, flash is not an option? (that will help moving on the the meat of the subject)I don't expect games to take up 50GB. Because the only way that happens now is putting on 20 languages of raw sound.
GTA, Everquest Next, Gran Turismo, Final Fantasy, Uncharted, Killzone, Metal Gear Solid, God of War. These are AAA system sellers and will require much more than 16GB. At least some of these must be in the launch window.
LA Noire on PS3 is about 40GB downloadable with the DLC, and it could use some higher resolution textures and models.
