I don't think Natal can distinguish fingers anyway.  It can measure where the arm is pointing.  My question is whether it is a cube with volume of 4 cm?  Or is it a cube with 4 cm on each side?

If the x/y resolution is 4 cm, that's even worse and you have to cut that in more than half, with on-screen steps of an inch and a half.

It is pretty clear that the 4cm correspods to xy resolution. Let's assume that the tof chip is an _expensive_ one with a pixel count of 320*240. with those 320 pixels you have to cover max 4 players hopping in front of you - about 5-6m wide space/320 = 1.6-2cm per pixel. The z resolution could be better depending on whether the tof camera depth resolution is programmable or not by developpers. 4cm z resolution would indicate the depth space covered is 256*4cm = 10meters which seems a bit high.

Is Natal using TOF?  I read they are just reading the light intensity reflected back from the IR bursts.  I thought TOF based it on the time it took and not light intensity.  I am assuming they would correlate, but TOF is probably more expensive and accurate.

I read somewhere it does... Intensity based systems may be less expensinve, but their accuracy may be disturbed by countless factors in an unknown environment (in the robotic meaning), as are every users' living rooms.

Given this latest news, and having SPE's that are perfect for the job and not fully exploited by games yet, Sony could end up with smoother, and more easily applicable to games, SW only solution for its camera. It's quite likely that Sony knew this before us and this would explain why they were so quiet about their own system, waiting for MS hype bubble to burst. Natal camera is more advanced, this is undeniable, but crippling it MS risks making its user experience more awkward than simpler solutions' ones. What's worst for MS is that this way it not only uncovered its best cards, but it discarded some of them instead of playing them. If MS wanted to be first and unchallenged, it had to accept to lose some money, initially, did it expect other companies to take the burden in place of it to bring the chips to mass production and commodity cost and still be first on the market?
