Microsoft doesn't view Valve as a competitor in the console universe, Microsoft President of Interactive Entertainment Business Don Mattrick said during Microsoft's TechForum. Valve is "doing some innovative stuff," Mattrick says, but when it comes to direct competition, "no."

"The scale of products and things that are being brought to market are probably a little bit richer when I look at Sony, Nintendo, Apple and Google," he says.

Valve boss Gabe Newell recently noted that Apple is the Steam Box's (Image above) biggest threat, since it already controls such a large portion of the market with the App Store.
Nat Brown, the man who gave the original Xbox its name and former Microsoft leader, also sees Apple's potential to own the console game.

"Apple, if it chooses to do so, will simply kill PlayStation, Wii U and Xbox by introducing an open 30 percent-cut app/game ecosystem for Apple TV,"
