I thought it might be too good to be true, but I can see the sense in what they are trying to do. This extra data might eventually be used in an interesting way for game-play, or I guess if one is using a GPS game inside, a system of gesturing could be used for indicating where you are.

It is not about dead reckoning. If you are sitting in a movie theater, there is no need to power up to get a location fix, but other movements may indicate an opportunity to grab some satellite data to update current location. The built-in temp sensor can be used for this purpose, too, (it may be warmer or colder outdoors) but it is also used to help calibrate the internal clock of the SSIV chip for more accuracy.
