InvenSense still not in the Watch -2

Chipworks is out with a Series 2 Watch tear-down and it reveals that the motion sensing chip is from STMicro and the microphone from Knowles.  Apple should have been designing InvenSense parts into the device by this time if the relationship is growing.  Without that, it's probably just a matter of time until iPhone gyros are second-sourced or replaced entirely.  That would be a crippling blow for InvenSense.
