@kitler: In the interview (which I can't find at the moment
) only the traditional controller was mentioned, so I'd guess it would generally be limited to head-tracking and voice commands unless they come out with some hypothetical Xmote.
In the event that they do include a controller, I'd agree cost might be an issue, though but probably no more so than in the case of Sony's PSeye + 2-4 controllers. Frankly, I'm pretty pessimistic about any of this new motion control stuff gaining enough adopters to be viable unless they bundle the living hell out of it (cheaply). It just feels too much like they're trying to change horses in midstream.
