Well, I sure hope it is Flanker 3.
BUT F2 didn't replace F1.5 for me....F1.5 had so many good features that F2 didn't have....F2.5, however is now my flanker sim of choice.
Maybe we'll he to wait till LOMAC 1.5 until F2.5 is obsolete...
But as I said, LOMAC will be (hopefully) Flanker 3 (with a couple of American designs thrown in to help sales.....)
