Earlier this month, while promoting The Mummy, Tom Cruise teased that that this Top Gun sequel will be called Top Gun: Maverick, because he "didn't want a number" in the title.
This report did reveal, though, that the story will follow Maverick, who is now a flight instructor, "teaching the young macho pilots how to do it." You may recall that, at the end of Top Gun, Maverick teased that he would like to teach pilots at the Top Gun school, and it seems that he got his wish, more than 30 years later.
Tom Cruise also stated back in 2015 that this sequel will have "real jets" with no CGI, hinting that he wanted to get the Department of Defense involved so they could use actual Navy fighter jets.
Whether or not this will happen remains unclear, but it seems that this sequel is actually happening, after several years of delays.
Tony Scott had teased a similar drones story line before he passed away, but it hasn't been confirmed if this aspect of the story will still be used in Top Gun 2.
