Microsoft may be readying a new weapon that could shift the balance in the interminable console wars: the mouse. Wait, you say, didn’t they promise that years ago, and aren’t there peripherals already available? Kind of. But going whole hog into PC-style controls allows Microsoft to create powerful synergies with Windows, performing a flanking maneuver against arch-rival Sony.

Mouse and keyboard is, of course, the control method of choice for many games on PC, but it has remained elusive on consoles. Some fancy accessories have made it possible to do it, and years ago Microsoft said it would be adding in mouse support to games on its console, but the feature has in practice proved frustratingly limited. More on-screen pointing has been done with Wiimotes by far.
