Amazing that the only people that care to argue false advertising are PS3 fans, and do not really care about the series.
As DOATS said, there was a demo that launched before the game came out, and has been one of the most successful demos that XBL has ever had. If MS wanted to false-advertise, why not wait till the game comes out, then put it up?
This is on the same level of people buying Sonic & Mario at the Olympics, and expecting a 2D scroller.
Back from the dead, I'm afraid.
