I honestly could see MGS:R on 3 HDDVD discs for 360. Think about it, the graphics will take a ton of disc space. So, unless all this time, they're unspecifically meant the PS3 version's graphics were going to surpass MGS4, while the 360 version wouldn't even do that, expect multiple discs for 360.
Remember, they had to remove some content from MGS4, because not even the blu-ray could store so much information at that time. And, with MGS:R missing MGO, it has an extra 15-20 GB to work with, so, the space is there.
