Geeze Toulouse, way to kill some more sales by opening your mouth! ^_^
Anyone should know that countering backlash from the community with more backlash only hurts your own business. Sure there are some unique situations where it works, but this is not one of those moments.
I wasn't planning on buying kinect in the first place, but even if I was remotely interested, I wouldn't be anymore after reading something like that.
Let's face it, your best bet is to just admit that it's gonna be an over-expensive kiddy toy and get it out in the open, blame Nintendo for making gamers everywhere skeptical about motion detention gameplay, and move on.
Most gamers don't want this product, so pushing it on them isn't going to help you, just hop over to the only audience that's interested in this thing and focus on them instead.
