I fully expect we will be able to... Just unsure of day 1 availability
Though if people want to use online or B&M, it's their choice
I also don't expect games to be consistently pushing that 50 gig barrier, either
I wouldn't be suprised if they do, 360 games for example all extract to ISO form at a size of about 7.4 gig, no matter if the actual game uses that much data, i bet next gen games will be the same.
