I suggest people stop assuming all these rumors and just shut up till msoft announces their official specs the start of this generation everyone said xbox was doomed now they're the leader everyone is saying it again I don't see why the Sony fan boys want msoft to fail if sony doesn't have a equal competitor in the market they could shove 600 dollar consoles down your throat like they tried to do before personally sony fans should be proud of how far msoft has come from basically last place to being the leader and forcing sony to drive and innovate its platform everything they announce at their conference is basically xbox live anywhere from msoft 2006 press conference btw which was when sony basically lost this generation because moft had so many games i think a lot of people forget.

msoft always start their generations the same they start with games before going full blown media plus so people expecting them to fail and say the only have kinect stuff should be careful what you wish for as for the people who say they only have halo that franchise has outsold all of sonys new ips combined so when you say they only have halo their franchises move consoles unlike sony's. Declare xbox dead on arrival all you want i for one love seeing an american company dominating and taking it to the companies that originally owned that space.
