well, the ds isnt considered a gb i guess, but it should be, and it was pretty revolutionary, i'd have to say. but, the next gb after micro? well, i think it'll be less 'box' shaped, and more like a console controller, kind of like a hybrid controller/gameboy. it will be backlit of course. the best thing it can do is have a lot more capabilities for the games, allowing them to be bigger and better...hopefully it'll have wireless conectivity with the rev too (which has been hinted).
