[quote name='Romeo']How do these collection sets work for 360? I buy all of them for PS3. Will there be three discs?[/QUOTE]
Sometimes they're on 1 disc, sometimes they're on 2, I don't think there's ever been one that has been on 3.
I know MGS collection is on 2 discs, and I'm pretty sure DMC Collection is on 1 disc. Microsoft allows 1000 gamerscore per disc, so Devil May Cry has 99 achievements for 1000 gamerscore. Kind of crazy, and the reason I buy all my collections on PS3 as well because each game gets it's own trophy set and platinum.
My guess is this collection will be on 2 discs. The achievements have already been uncovered for this game, and "Contracts" and "Silent Assassin" together were worth 1000 gamerscore, with no mention of any Achievements for "Blood Money". My guess is that "Contacts" and "Silent Assassin" will be on 1 disc, and "Blood Money" on another disc and have another 1000 GS, probably the exact achievement list that the original release of "Blood Money" had.
