@Le Shorte: "A 20% increase" is just misuse of statistics, really. Apple did the same thing not too long ago.
"We have increased by X percent, the PC has only increased by Y percent."
It's not a valid comparison.
Why?
Let me use Call of Duty: Modern Warfare (the first one) as an example. A few months into its life cycle, it had sold roughly 14 million copies. If you added numbers from other sources, PS3 + 360 (not sure in which order) had sold 13,5 million copies, leaving reasonable deduction a measly 500K for the PC platform.
In this context, with only the one game as an example, if PC sales would go up by 20% it would still just be around 100K additional copies, which is less than a 1% increase for the console market (which would be some 135K copies).
Because of this, "20% increase! OMG!" is just playing the tunes of the journalist who wrote the article when he should have been learning math.
In most ways, the console discussion is kind of moot, as well. People still play games on all platforms. It's just that the consoles are a lot more profitable, because the piracy is minimal. I.e., people pay to play.
Either way, the more people that play games, the better!
