Epic makes awesome multiplayer games and awesome engines. Gears of War 1 was rated at over 90 on Metacritic and Epic being a top tier developer with an Engine to sell has every incentive to make GOW2 as big as it possibly can. Furthermore, this time around the GOW franchise has a much higher profile, so to sell all it has to do is be equally good while fixing a few of the little faults with the first game. If it does this, there is no reason why it shouldn't sell over 5 million units in its lifetime. So you see? It's an Epic Winner. Furthermore I think the more anyone attacks the game due to it coming on the wrong system, the more I think they are afraid of it. AAA game from an AAA developer.
Tease.
