I think the Wii is most likely to hold the top position end of 2007. No big surprise, given my general opinions on the matter, but it has more potential to host creative games that will bring more people into gaming. We've mostly been using variants on the gamepad interface since it arrived on the NES, and joysticks for far longer. Sure, there's the occasional one-off interface like the dance pad, drum controllers and guitar attachment, but the remote/nunchuk combination has the potential to allow for a wider array of interfaces that simply didn't exist before. It's these interfaces that will grow the market, and increase the Wii's market share beyond the typical gamers.
