4 E95s are indeed planned to be removed from the schedule over the course of the summer. Affected bases have been announced as BHX, SOU, EXT and BHD.
I doubt very much that these aircraft are to be sold. I suspect that the intention is to release them from scheduled services where loads are currently better suited to the Dash, and to free them up for a variety of charters and/or leases, where the E95 has a greater potential.
Lucrative work if you can get it.
