Microsoft and Sony both already make tablets. But Microsoft's Windows Surface tablets are mainly designed for work, and school, and Sony's Xperia Z Android tablets are mainly for entertainment, and basic work tasks.
I think Microsoft, and Sony may create a Gaming tablet with removable gamepad controllers if enough people are interested in Gaming on a tablet with a removable gamepad controllers, and want to play Xbox and Playstation exclusive games on a Gaming Tablet device with physical controls.
I guest, Sony can make a bigger more powerful version of the PSP Vita to create a Gaming tablet experience. The Vita already has a touchscreen and touch pad on the back of the console, so Sony can make a Vita with a 6-7 inch screen, more RAM, faster graphic chips, and a more powerful processor, so it can run higher quality games.
