I doubt AW will offer a service as they didn't submit a PQQ. Eurocopter did though!
I would suggest that no OEM will offer to prime this as there is a piece of pie in it for all of them with the right consortium and better to remain agnostic.
There are many other players interested aside from the usual suspects always talked about here, and just because they don't currently have a footprint in the UK does not mean that they are not perfectly capable of doing the job and doing it well. Might be a nice change to see some fresh approaches out there.
