Asymmetrical gaming -- it's the new buzzword amongst gaming exec types. It's what everyone expects us to want. Everyone's finding their own way to do it, whether it's via the Wii U controller, the Vita, or just tablets themselves. Microsoft wants to use its surface tablet for this task, and it wants to do it as early as the release of Halo 4.
Speaking at VentureBeat's Gamesbeat conference, Don Mattrick confirmed that Halo 4 would be compatible with the Surface. He didn't go into detail regarding how it would work, but it's interesting nonetheless.
I'd imagine the integration is most likely minimal, but it's a first step. You might say we've just scratched... the surface?
(I'm so sorry...)
