On the subject of the Wii's D-pad and single button, I think the issue here is that "secondary" inputs have always sucked. The analogs on the Dual Shock. The D-pad and C-stick on the cube. Of course, some things make the problem worse than others (like the puny size of the Cube's D-pad). I think the Wii has the right idea in putting them close to one another, but the "freehand" style will do more to make it harder to shift your hand position than anything we've seen.
I'd like to see a D-pad on one end of the Wiimote, and a set of four buttons on the other end, so you could flip it around to make good use of either method. But I don't expect Nintendo to make any changes to it's design.

Think we'll ever see and MMORPG on the Wii? Up until now, they've seemed a little scared to leave the PC, but they really wouldn't play all that differently on a console.
I don't think it will happen. (snip)
The latest EGM says in their rumor section that Square has a Seiken Densetsu (Mana) MMORPG in the works, exclusively for the Wii.
