It's amazing how a few people seem to be wishing this to be true, when it won't be the case. The vast majority of games have better load times on 360 vs PS3, which is probably the only factor a DVD9 has over a BR disk, as been mentioned already. Just because this is lead on PS3 doesn't mean it'll effect 360 load times; look at FFXIII or L.A. Noire (something I would honestly expect a lead version to have ia slightly better visuals and it seems both versions are identical regarding that from gameplay). And those have multiple disks, which reminds me:
An early importer from GAF said the back of the PS3 box mentions the game is less than 7 gigs, which honestly is surprising to me.
That said, 360 version was most likely not installed vs installed PS3 version. It's not a fair comparison and I bet my account that 360 version won't have 40second load times. Anyone wanna bet theirs?
Also, has anyone come to a conclusion why the game was crashing so much on stream? Haven't been in the topic since yesterday and on a crappy phone atm.
