Speaking for myself: I will not buy any more WW2 modules from ED until the DM is released, the promised AI planes are here and we have WW2 radio (that's currently a big immersion killer in the "Big Show" campaign for me).
Even then I will take a hard look at the remainung bugs in the 190, 109 and Spit before opening the wallet again - and that is not because I don't want to fund them, but I feel it's the wrong way. Every new module needs to be maintained, just as the old ones. The more modules, the more workload (without revenue).
