B&W 805 D3

Does anybody here own the B&W 805 D3? I just happen to read about this new model although it was launched sometime last year. Apparently the long-surviving Kevlar driver had been replaced by the new Continuum driver in the all new 800-diamond series now in their 3rd generation. Is the new Continuum driver a huge departure in sound quality from the previous B&W models which are on the Kevlar?

Is there a significant difference going from the following iterations :-

Nautilus 805 => 805S => 805 Diamond => 805 D2 => 805 D3 (new Continuum driver)

Any thoughts would be appreciated.
