Sorry, I don't think there will be a X-box slim. Well mabye if the brick at the end of it got bigger. It will take serious marketing for a peripheral to change the market. The only one that ever really did anything is Wii Fit and I think the Wii was already kicking everyones ass so it's hard to tell.
