Colin - Thanks for your great industry insight and humor on the GameTheory podcast. It was a favorite of mine for more than a year, even before the GT site. I will miss the banter and the intelligent discussion - something not found on the fanboy podcasts. Best of luck in your Edge endeavors.

I think Nintendo is really smart -- they could easily continue to print money for a few more years without innovating simply on the insatiable demand for Wii and DS alone. Yet they're already developing another market to penetrate. I know that my DS stays at home. Once you've added a camera, well, maybe I'll keep it with me, show my friends, etc.

I've read on Kotaku (I think) that Iwata's goal is one handheld per person - a goal that none would dare contemplate, yet they're on their way to making that a reality, numbers-wise anyway (1 of 6 in Japan own a DS). As for Wii HD, the only chink in their armor is keeping up with graphics - as more sets in the home go HD - this strategy makes sense.
