I think the PTZ on the rear of the tower is actually being used to frame an angled shot towards the sofa, particularly when they use the video on the right hand wall for interviews (which I don't think they used on Monday). AFAIK, a standard straight on shot is used from a full sized camera near the rear of the studio when the weather is presented.

Judging by a shot just seen the camera is for a guest sitting in the middle of the sofa - so will probably be a regular appearance.

I'm not sure though that this camera isn't also doing the weather. It looks too tight to get the shot without the tower intruding.
