I'm having a really hard time caring about MW3. Details on the game's MP are scant to say the least, which is a bit concerning. Maybe they're behind on development, maybe there's nothing to report since it's just an MW2 rehash.
The article makes a few good points, but whoever wrote is a moron. Statements like "anyone can jump into xxx and do well.". That's a mathematically ignorant type of statement to make; after all, half the players in a match will do well, half will not. That's a general statement for sure, but you get the point.
Personally, I do think BF3 can out sell CODwhatever, because people are clamoring for something new. BC2 was new, but the execution on consoles was a disaster... This season is DICE's to lose.
