Halo 4 kicks off an entirely new triolgy in the Halo universe, picking up where Halo 3 left off, [Spoiler Alert] with the Master Chief stranded who knows where, after being caught up in an explosion when the last Halo ring fired. It is said to be released by near Christmas 2012.(-fail!-) Although it is too early to forum about, it will still most likely be a good forum. It'll be sad to play through a game without one of Martin O'Donnel's epic scores, though. :(
