One of the threads at SimHQ mentioned that RoF seemed to be withering. I just got back from checking it out. There's a thread entitled "The Future of RoF" and the general tenor is that it's time to hold the wake. "Battle of Stalingrad" has apparently done so well that 777 is now full bore developing "Battle of Moscow". (Why not? Same adversaries, same planes, same snow, etc.)
The drips and drabs of information that the boyos have been able to elicit from the Devs seem to say, "Well, we haven't completely turned our back on RoF, but we're completely tied up on BoM so don't expect much, if anything, in the near future."
Too bad. It was/is a great looking sim tho' I think WOFF overtook it.
