Don't forget that BE have the final 4 Q400's on definite order due in Q2 and Q3 next year, so they will need to find quite a bit of new work to keep them occupied.
I'm aware they are still hanging on to the last 2 ex-SAS models right now and there have been rumours of some of the very early indigenous ones going too, but I'm sure when these deliveries were deferred to 2011, it was intended to use them for network growth.
