You will have the new clouds to add some diversity and in Take-On getting some of the addon fighters up to 40,000 feet was a decent experience.
I don't know the size of the Limnos map compared to Take-On's South Asia but it took between five to ten minutes with a Mig35 at around 750knots to go corner to corner of the map.
Standard A2 aircraft take a lot lot longer.
They have the maps size to increase the speeds or they can keep similar performances as A2 to make the map feel even bigger, with the whole map surrounded by ocean it really wouldn't be a problem to up the speed as you would never really run out of map.
It would be nice to have some logistics based aircraft missions too, for those of us who can't hit shit in a fighter or ground attack aircraft.
