Over on the Facebook Model X owners group, there is a picture and discussion of a new camera housing that new Model X seem to be getting. The housing supports two cameras, although so far people are still only getting one camera in the new housing.
The two guys who got these (one with a replacement windshield) say there is as yet only one camera. So this is a new housing part, but no extra AP functional parts yet.
