Hmm... My guess would be
1) Remodel of one or more planes
2) Addition of a plane
3) Addition of a GV.
Hopefully all 3.

I would hope they remodel the B-26. From what I've gathered, what we have is what it was when it first came out. For the addition, I hope the He-111 H-11. For the GV, I'm hoping for the Crusader Mk II or Mk III, or the BT-5 or 7.
I must admit though, that PZL p24 looks nice.... Too bad we won't have any Do-17z's to shoot down with them.
