BMS will be done when the BMS devs decide they are finished modding F4.

It's their passion that they are kind enough to share with the public. They make no money off what they do and aren't concerned with how many people are flying their sim.

I think what you mean is that people will be done with BMS if DCS can come up with a dynamic campaign engine that can hold a candle to F4's DC.

But I'm not holding my breath.
