I predict a new DS design this year or early next year

I'd like to see the DS get slightly larger screens, a better d-pad and buttons, OLED screens and a longer battery life.

I don't see myself upgrading from the DS Lite though, it's good enough already.

 Larger screens would wreck it, it would cause pixelation on the "older" games.
