The XJ8 4.0 and 3.2 X308s both used XFs, so they've been leaning that way for a while.
My experience of the Jaguar auto box - ZF - albeit the six speed, is that it is considerably smoother than the 7g plus in my current E Class, which I find clunky in lower gear changes, despite the software update. There are other minor design faults with the 212, but overall it's the gearbox that mars my total enjoyment of the car.
