I do think a screen on the controller is possible- Nintendo has tried it before, but not seen any real success due to the need for a portable system per player, AND the link cables. But it won't be the main focus; I think the IGN mockup is more likely than the OP. But I don't really see either as good options, as motion is too hard to do with either of them. The motion, especially for backwards-compatibility with the Wii, will be the toughest part.
