I predict a new DS design this year or early next year

[ChichiriMuyo]

I agree with your assessment that there will be new DS hardware this year, but disagree with your implication that the Wii will not be getting a redesign in its lifetime.

Chances are, there will be some built-in flash memory to take real advantage of the Wii's ability to deliver DS demos, and it will spark a much bigger increase in sales than the GBA micro engendered.

But, again, I have no reason to beleive a Wii remodel wasn't in the works before the Wii istelf was launched. I am fairly certain they planned an update to the Wii long before they started pumping them out in the factories.
