I don't doubt that whatsoever, I originally was going to expand on what I meant but it didn't come out right, so I removed a large part of my response.

I think the problem extends mostly from the poor choice of platform - the PC

In the greater consumer market (think non geeks), the PC is generally tethered to places that don't have much open space associated with them, eg on desks either in bedrooms, home offices or out of the way places.

I think this is the greatest restriction placed on them, especially for a control device that gets you ducking and diving through a magnetic field.

This is why I don't think the Wii has anything to worry about, it's a dedicated gaming device thats nearly always permanently connected to the main TV in any household and that particular TV has plenty of open space in front of it for swinging your arms around.

Now if they were bringing this out for one of the other consoles with dedicated developer support, that's a whole different story, but right now as an additional controler for a PC I don't think it will do too well.

Great Idea, poor execution IMO
