The thread title says it all, how powerful will the 3DS successor be?
3DS is somewhere between PSP & Wii so im gonna go ahead and say its successor will be somewhere between Vita & Wii U in power. it will have a 720p screen and can handle downports of many Wii U games just as 3DS can with Wii (DKC Returns/Monster Hunter/Xenoblade).
When the herd loses its way, the shepard must kill the bull that leads them astray.
