Not a leak. Miniatures Market, Noble Knight Games etc have the 1941, 1942, and both 1940 title reprints (under Renegade Games) available for pre-order.
No word on Anniversary, but that and 1914 are logical reprint choices. Hoping the delay is so they can design additional sculpts for both titles, and make them a true “must-purchase” even for existing owners.
If Anniversary is the only edition with Pz IV and Valentine tanks, P51 Mustangs etc then it will drive demand - I’m sure that’s one of the considerations for how to release it.
