Its doing pretty well - but I see it mainly as a migration platform for gamers that used to solely play PC games.
GoW, BioShock, Halo, CoD, Orange Box --> all classic PC games (shooters?) that have migrated to the console world.
I can't think of a lot of classic NON-PC games that have done (really?) well on the 360. Dead Rising? Mass Effect? Assassins Creed (PC as well?).
Much of it comes down to strong online support, plus a control system that isn't *too* dissimilar to PC (given that mouse --> analog stick).
...
Its still a very solid console, with some very solid games. When I get around to buying another console (god knows when...) it will almost certainly be a 360.
