Even this is the fact sheet thread, speculations are always entertaining.
I really hope all new unit costs make it into AA42, AA gun is not so important, the naval rules have been confirmed, and so probably AA42 will have the same naval units costs as AA50. I do hope that bombers will be priced @12.
The new SBR rules are better than the old ones, so it should be included. I don’t expect any NO system similar to AA50, even if it’s an optional rule, it is perceived as too complex for an updated version of Revised. As for new TTs, probably not, but with only one or two new TTs, this would be a great improvement.
I didn’t think of a new setup in AA42 which differs a lot from Revised. There might be some CAs, and 2 more German units in Africa to make a better balance.
