Personally I don't think they will. I suspect they will try to release it across all platforms at the same time.... maybe even for the Playstation. Was just a joke hence the smiley

Not being a 360 user was not aware the market place for the 360 only updates Tuesday (which is inconvenient)
The longer it takes the better it will likely be. Don't wish it here faster than needed

I agree. I hope they managed to prepare all the DLC for Playstation. I made a friend discover The Elder Scrolls Series but he has a Playstation and I"m kind of disappointed for him that he can't explore Dawnguard and such on this platform.
And now, speaking about the 360 timeline, and as uncertain as the idea is about 12.12.12, I don't think they would rush with Halo 4 coming out in November. Well, I don't think they should.
