TrueMotion's amazing 3D game controller makes the Wii look like a toy

I used to play with Ascension's Flock of Birds [1]. You can get pretty accurate 3D position and orientation.
Though these older systems were pretty expensive (~$10K), I wonder what would be the price of these new toys.

Of course, it will have to come down farther if video game manufacturers are going to consider spending $ developing features for people using these. Right now, spending time designing a game for this kind of interaction means you'll be able to sell it on the Wii.
When the PC, PS3, and XBox start having these kinds of input devices, game (and software) manufacturers will take much more notice.
BTW they say it will ship for PC.
Why? Simple: it removes complexity. You can do things more intuitively and more subtly (think d-stick versus d-pad), and you can suddenly do more with fewer buttons. You need one less stick for aiming at the screen. It makes games better - more involved - while at the same time allowing more people to play it.
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
