To be fair, noone outside of virtual reality type platform developers (the Virtuality system comes to mind) has really developed for a system like the Wii. It's an interesting platform primarily due to its control method. Software that's given more time will tend to utilize the Wii's strengths. The same can be said with any new hardware platform to be sure, but even so the Wii is not built to be a typical game console. It was built to provide new types of gameplay out of the box. We'll be seeing an evolution of 3D interfaces on the Wii, and I for one find that quite an exciting prospect.
