also of note: the kinect can already see 40-50 cm in good conditions.
i'm curious if they've increased the accuracy in this range,
sacrificing far-range accuracy? this would be great news for people
working with portraiture/face biometrics/hand tracking.

Possible. Or maybe the quantity of people asking Microsoft for this
more recently prompted them to contract PrimeSense to do a
modification.

Isn't the only real issue with using the Kinect at close range the
brightness of the laser pattern at close distances? The IR image
appears to just get washed out when you get too close - my first guess
is that they've got a way to adjust the brightness of the IR projector
(or simply replaced the laser with a less-powerful one). Or is it
that the individual dots are too large and collide with each other if
they haven't had a certain distance to spread out over? (would a
weaker laser resolve this, or would you need a different diffraction
grating?)

in my experience, near-range sensing seems to fail for two reasons:
1 overexposure. a lower power laser would help. maybe even an ND filter.
2 defocus. this requires changes to the optics.

Possible, depending on how Microsoft implements this. Even if it
doesn't require new hardware, we'll still have to work out the
flashing procedure - there's no guarantee that it's the same one used
by OpenNI's Sensor.
Since even USB filter drivers can't log the USB transfers from the
Kinect (it shows up as a different device type), this may require
dumps from a USB hardware analyzer. /me waits patiently for his
OpenVizsla
