Etap Red 22 11 Speed Rear Derailleur A2 vs A1 overview

The differences between the Etap Red A2 rear derailleur and the original A1 version. Couldn't find this information anywhere on youtube, so thought I'd share my very amateur view.
SRAM appear to have very quietly released this upgrade with heavily revised internals including the Orbit fluid damper and new motor (from the AXS range?) and new, larger pully wheels.
I don't know how it rides yet - further review to follow if you want one. Let me know in the comments below.
