I'll make an uneducated guess on bases.

AAG seems keen to bring more regional flying under the Wholly Owned umbrella (or it seems to...)

Take a look at who does what - This forum contains many threads about Air Wis - if that's taken over by AAG, the new base could possibly be in Boston (being a main center) or Norfolk.

If Mesa relinquishes the AA side, there could be a new base in Phoenix. DFW is already covered by Envoy.

Or I could be totally wrong, however idle gossip and speculation is quite satisfying!
