dont loose hope on forge they havent let anything out about it but im sure it will be better then halo reach forge (it better be) and the game will have custom loadouts aromor will effect game play so yes the game will have large changes but still be halo. i bet when the next xbox comes out halo 5 will have much larger games. 343 has said halo 4 is the best looking xbox game to date and that they have pushed halo 4 to the limmits on the 360.
