When you look at the massive storage of blu-ray, i'd say yeah it's possible, i think you're going to start seeing multi-generational compilations of games, like up to X and XII on one disc.

Although FFIII presents a problem since the only versions are the original NES, which no one would want to play, and the DS remake, which Nintendo wouldn't let happen. So it's tough.

Digital Distribution is just as likely, but we've yet to see it. I think once FFXIII is released we'll start seeing more of these things on the PSN Store and XBL Arcade.
