Presumably that angled drive at the front goes into the MRGB but he talked in the video about taking the power from the rear of the engine.
Does that mean they still have a shaft running forward from the rear and underneath the engine and if so, where is the TR drive coming from?
I can't remember if there was any talk of an electric TR on this but if you take the TR drive from the engine instead of the MRGB you have no TR drive in the event of the engine failing.
