I got some questions on my blog post that you should not by a Wii at the moment. The key question was about whether this is just a teaser. Well, look at the demos they did at E3. You find them here: http://www.xbox.com/en-US/live/projectnatal/
If you're looking forward to Project Natal, be sure to check out http://www.project-natal.com for all the latest news and info.
Wii has been demolished. Microsoft keeps getting better and better with the 360 features. I'm so glad I bought a 360.
