They seem to be using just the gyros.

    There are already some accelerometers being made that way ! I even have
a sample here and it works just as well as analog device "classic" devices.
I can not remember the name of the company right now but it was founded by
Ex-Analog devices employes and one of the investors is Analog devices ! My
project that would use the components did not move as I thought so I can not
say anything about price.
