EA already do the same thing.
Although I doubt they'd go for it, this is a superb opportunity for Microsoft to insist on absolutely no passes of any nature from any devs, then mass-market the XBOX with that point in it's favor. That would completely f*ck over Sony.
Codemasters did it with Dirt 3, no idea if they have with other games. Warner Brothers are doing it too as well as a few of their recent games have used it (with one, Fear 3 being criticised for it) so I'd expect their future games (like Arkham City) to use it as well.
However, MS can't insist on anything because EA include online passes with the 360 version of games as well. In fact, the PS3 online pass could (I'm not too sure) be better of the two because a lot of 360 content is restricted. While PS3 content can be accessed by all accounts, 360 accounts are often excluded from accessing material premium content downloaded on another, so it's possible MS actually requires multiple online passes like it requires multiple XBL subscriptions.
