The Xbox 360 is more of a casual gaming system, see Halo 3 and Gears of War. RPG's aren't readily associated with Microsoft or the Xbox 360, or not as much as they are with Nintendo and the like. The case is the same with Sony. Now I'm not saying there will never be, or aren't any RPG's for the Xbox 360 (let me stop for a second --- now let me say now that I mean commercially released and/or advertised RPG's; every game system has obscure types of every game, just not it's main function), but RPG's don't extend to the main demographic of Xbox 360. Nintendo caters to this type of gamer though, as Sony tends to gravitate towards...well, I'm not exactly sure. But I'll go with Action/Action Adventure. I'm not sure of this, I'm just saying I have a lot of PS2 Action/Adventure games, and I've seen many released for the PS3. That's why there are three different consoles, they cater to different audiences. So, in conclusion, RPG's could be commercially released on the Xbox 360...just not any time in the next century.
