Microsoft is announcing something later tonight and no-one has any idea what it will be. Barnes and Noble officially said that they have nothing to do with whatever is happening today so the rumour-mound is eagerly hopping to the next rumour: an Xbox Surface tablet; a 7-inch tablet that's probably going to play nice with an Xbox.
Supposedly, the leaked specs of the Xbox Surface, which come from Shifted2u, show a 7-inch 1280 x 720 tablet device with multitouch and ARM processor that can connect to a "stationary computing device" to presumably stream stuff to and fro. So would that make the Xbox Surface a glorified Xbox controller or Microsoft hardware for its Smart Glass technology or just a Microsoft-made tablet that shares more Surface features than Xbox gaming qualities? No one knows.
