I think they might redesign the controller a bit, like concave triggers and maybe they'll alter the looks/size/weight a bit - feature wise the biggest difference I can see them include is a backtouchpad like the vita has
while holding the DS you usually have either your middle or your ring fingers (depending on whether you use 2 or 4 fingers for the R/L buttons) at the back of the controllers, so they could be used for some kind of input there
