Ehh it might not be the end of halo, If you watched after the credits it shows a sean in witch the main charatore(What ever his name is) is alive, and freezes him-self after telling the little robot thingy to wake him when they need him, I dunno I didn't play the game that much, anyway microsoft most-likly doesn't really give a shit, they make games to make there console popular, they already have enough money, as long as it is made for Xbox360, microsoft won't care.
