John Bickerton who recently announced he's joining Arriva (was previously head of Engineering and Innovation at Reading Buses) to work on the move to low carbon put a tweet out about it earlier, so potentially. 

I can't see GNE going for them, Martijn seems very keen on ADL products (and Yutong for low-carbon/electric). Stagecoach NE, it would be a shock if Stagecoach ordered non-ADL - however they do have some MCV bodied B8RLEs on order for Orkney.
