Makes sense when you think about it. I even find it hard to fathom the mysterious PS3 Wipeout thats rumored to be coming at some stage could even half fill a 50 gig Blu Ray disk. No matter what the detail or how uncompressed the audio it just doesn't seem the type of game that will ever need all the space.

Games like future GTAs could potentially fill it due big maps with lots of details etc.
