So a company in extremely close ties with Sony has doubts on NATAL.
*Rolls Eyes*
Some of those things may not make the final version of NATAL. We are going to see the final finished product this year. Notice last E3 they use the name 'Project' NATAL. This year the finished 'Project' will have a name.
Just because Sony showed the PS3 with a boomerang controller and changed it for release doesn't mean they falsely advertised. It happens during a working project.
