Motion Controller Lag Comparison (Wii,Move,Kinect)

Where did you get the 50ms of Wii remote lag from? I've seen the articles on the PSMove, and I understand where the Kinect numbers can come from, but I don't see how the Wii Remote is so much slower than the PSMove. They should be about even, not a factor of 2 away.

Two sources, one from a Wii Remote programming guide: "To avoid the random state put a delay of at least 50ms between every single byte transmission." http://wiibrew.org/wiki/Wiimote and a quote by Rich Hilleman, Creative Director for Electronic Arts who during the Hot Chips symposium in August 2009 commented on the "100ms delay inherent in the Wii remote", which I assume referred to software and hardware. I suppose you could get even more precise numbers if you took the IR scan frequency into consideration (I didn't bother to find that out).

EDIT: Found my third source again: http://www.pitt.edu/~nak54/Wiimote-poster-a4.pdf This is about building a low cost motion capturing system with a Wii Remote, and it says about the hardware: "Latency in acquisition: 50ms"
