The Wiimote IR camera by itself is 100Hz in raw acquisition rate, but then the raw data has to be processed, laid out in a standard format and transmitted over Bluetooth by the embedded silicon, again at 100Hz. Indipendently from the acquisition and transmission rates, the time shift from acquisition to transmission builds the latency.
According to damnyouall's third source - it looks like a nice, independant measure set - the effective latency from IR detection to transmission is indeed about 50ms.

Apples to oranges.
KZ2's so-called lag is from button pressure to on-screen animation going through a running game loop. Kinect's ~150ms is from input to output going through a libray call simple output loop. You'll have to probably add something like another 70-100ms on top when you measure the same in a real game with rendering, double buffering, running AIs and so on. Pretty much what the OP said, basically.
Also let me say that these raw lag numbers have very little meaning. We organically perceive times and delays very differently depending on our actions and focus. Since my arm movement or footing shifting will last a good fraction of a second, those extra 100ms Kinect takes for full movement detection might very well be not perceived at all, whereas they could be obnoxious when guiding an on-screeen pointer or in discrete sharp actions like a button pressure.
Still: apples, oranges ;)
