As we have already seen many beautiful shots of the weather and effects on the plane like icing, i would be really intersted to see some high altitude scenes with the a320/747 drawing some nice contrails in the sky. Would be awsome to see a crowded sky with airliner air to air's in the next ifr episode. 

Really cant wait for the new sim anymore 😃

All those beatiful videos showing the sim..counting down the days already.

But still, where are these effects? 😃 how should i recognize ai traffic in the future on those many flights around the globe?😅

If it really was like they said in the Aerodynamics episode, then effects like engine condensation effects or even more, wing vapor, would just come out of the simulation engine without any further ado (think about each surface will have its own airflow, its own pressure, own humidity...). But I'm still in doubt that will happen. 🙄 At least I see no indication in any of the previews.
