What woudl be the next iteration of the Wiimote?

[shams]

Probably just an improved version of the current Wiimote. More accurate, more sensitive - easier to map 1-1 motion to it.

How about a small "touchpad" in the place of the A button? So you could do mouse rolls, or flicks with your finger? Or an "iPhone" styled Wiimote? No physical buttons (maybe an under trigger), just pressure sensitive.

Better speaker, maybe more memory. 

Whatever happens, it will almost certainly support the current Wiimote (most games would anyway). 

...

Or even better... the next DS becomes a Wiimote, with holographic projection from it. Play games on your Wiimote, or use it to control the Wii.

How about a portable Wii as the next DS?
