Yeah, I think Wii still has plenty of gas left in the tank. Like Reggie said, Wii still has a lot of untapped potential. NSMB Wii proves that with the right software a console can gain newfound momentum. I think Vitality Sensor and its premiere game will be the next big lift for the Wii.
With DS it's a different scenario. It's been on the market for a lot longer and both its hardware and software sales are starting to slide, particularly in Japan and Europe. I think its time is just about done in those markets. Though it's still going strong in the US, which is why I think the US will see the 3DS last out of the three.
