No, that would just be silly. iPad's sell well because they're portable and simpler than laptops for most multimedia and general tasks.
The Wii U controller looks intriguing, but if MS and Sony were to go in the tablet direction, it'd be a bit copycat. Maybe having an app for smartphones and tablets that could interact with the new console and its games. Like the Mass Effect 3 app but encompassing all games (if the publisher decides to of course).
