My vote is NO,
i don't se the use of these motion controller, really don't like the "unaccurate" wii-controllers.
and as it's not the "main" controlling system the games will be few and poor suported, it's like the xbox live vision, i bought it and thought i would be able to get some cool games and get my face on certain 3d charaters, and now a few years later there are not over 10 games that support the live vision.. that sux, like every fps similar should be able ot use it for more personal characters... but i guess it's just a dream, at least the fotboll/soccer/hockey games could support it.....
