Anyone seen the trailer of the most recently announced Ace Combat 7? It is going to be set in the Strangereal universe, unlike Joint Assault, AH, and Infinity, which were set in the real world. It seems that there will be a location called the Lighthouse. The airbrone superweapon with many propellers and parasite UAV's in AC7 is called "FAS". Two nations from past Ace Combat games (Osea and Eurusea) are probably going to return in this game. Ace Combat 7 is currently in earlier stages of development. I've heard that they finished writing down the plot and are working on the campaign missions.
I've heard about it and I am definitely excited about it. Although judging from the trailer, it appears that fictional aircrafts will play a larger role than in other titles of the series.
