I've said this in another thread, but I'll repeat it here. The idea of a 50 gig disc is great, but not for gaming right now. Sony needed to spend a little more time on it. We're not going to see any benefits of that extra space if developers have to double and triple the files on a blu-ray disc just to get faster loading times. The problem is the blu-ray drive can't read fast enough. BobbyBlu is right, we can just delete the unused files from the hd if space becomes a problem.
