yeah it's much easier to get killstreaks on this game but you can't use it on the demo
but like i said about the whole xbox/ps3 debate. most likely the reason why 360 got it first was because they had to money to bid on it. and that's one of the things that makes the subscription fee worth it.
as far as for ps3, if you guys haven't not heard/read articles online, ps3 will have a premium service that requires subscription fee sometime this year. so there you go for that, it'll make things even with xbox now. i mean don't get me wrong, ps3 has better graphics but the things that you can do on xbox is a lot smoother.
if it makes you guys feel better, i read it on ps3's website that ps3's will have an update that will let you play 3d blurays. and sterescopic 3d gaming's already out today! so that's a couple of things ps3 will have an advantage on.. if you have a 3d hdtv
anyways, i've come up with another glitch on the game, i noticed that when the server times out or you get disconnected from the game, you don't get the exp pts that you earn from that match. they should fix that or else that's another one way to throw your controller and end up breaking some of your collection
