I dont see how it could be more of the same, it has so many additions. Dual wielding, combination melee, interactive environment, boarding among other things should make it a big improvement over the last. One of the things that was great about the last Halo was that they took some concepts that FPS' had tried before, and they made them actually practical. People had tried vehicles in FPS, but they were never pulled off like they should have been. Grenades were usually a separate weapon, so you couldnt use them and a gun without switching in between. Also, you usually had to hold down a button for a minute to tell how much power you wanted to throw with. Halo made the grenade practical, and an integral part of the game. Melee attacks had been used before, but Halo actually made them do a lot of damage so that they were worth actually getting up close for. MY point is that I am betting that they will pull the new features off well, and that will make it a much better game than the first.
