The only real issue I have is that back in the '80s, the Cold War Era was still fresh, the Soviet's were a threat, and so much was unknown (as far as the public is concerned) about MIGs, they were their own scary-entity themselves.
Nowadays, who is our real threat? China? North Korea? Neither of them have any tech even close to rivaling ours, let alone how close the US and Soviets were back in the day. On top of that...considering our tech advances...'dogfights' are almost non-existent anymore. In the original, the Soviet MIGs were using "Exocet missiles capable of being fired more than 100-miles from their target." Besides the fact the Russians/Soviets never used them (total side note to the movie), today's tech is so far beyond this for the US fighters, I'm struggling to come up with the excuses they will use to include dogfights.
On top of all that...with the massive shift to drone-based fighters, unless Cruise is instructing the video-game jockeys, I'm finding it hard to determine when and where Maverick's skills will come into play.
All that said...I will happily go see it with all those guys on board! Maybe Val can lose a few pounds and bring back the Iceman!!!
