well 2009 had MW2 and NSMB Wii. Two HUGE sellers for the consoles.
This year we have Halo Reach, Black Ops, GT5, Fable 3, Donkey Kong, Wii Party for the consoles. I think it might be flat on the consoles.
The PC market is going to increase, but that is not that hard considering how bad 2009 was. Blizzard, the one and only on the PC market, releases 2 games. Last year they didn't release anything. You basically have to check blizzards releases to make a statement about the PC market.
Imagine not having GamePass on your console...
