E195
Yes, down to 3 E195's in the fleet this summer and I think all gone by Summer 2019. With incredibly expensive lease deals still attached, BE have no hope of making profitable use of them. We will still see E195's in BE colours out of SEN. Some routes there now doing well with load factor, even if we don't know about yield.
I wouldn't be surprised about the C Series, despite it's size. There are changes afoot at BE with a brand refresh imminent and within the business (as I used to be), it's a very well known fact that the CEO is not a fan of the Dash at all. I doubt it will go entirely: it's ideal sized (and very fuel efficient) for many existing BE routes. But route network is also being looked at.
Potentially interesting times ahead. I have also heard whispers of the ATR....
