Can we expect expansion out in time to be Christmas presents??

Hope so.

If all goes well I think yes, hopefully before. I should add it will definitely be around though.

an expansion ? mmmmmmmmmmmmmmmmmmmmm, wonder whats in it ?

Many things, 70+ improvements not including the new pilot animations, inline engine animation, new aircraft vibration and cockpit effects, new ground objects (new soldiers and so on).
Some changes are hinted / shown in the WOFF 2020 threads for this.

I'll post this in there too.

It is very nice to have something to look forward to. Immersion will be set on high as this wonderful sim continues beyond expectations. Thanks OBD!
