Ehh... not really.
Star Trek Online is everything a Star Trek fan would ever want. Yes, it's F2P, but all of the content is free and they give away great T6 ships at least 3 times a year, if not more. It's perfectly playable with no investment and they have a free expansion (Victory is Life) coming on the 5th that features most of the cast of Deep Space Nine reprising their roles as the Dominion joins the Starfleet/Klingon Defense Force/Romulan Republic alliance to help fight a threat to the Gamma Quadrant. That's not counting previous expansions which brought back a good chunk of the Voyager cast, as well Worf, Spock, Geordie LaForge, and even Chekov in his role as an Agent of Yesterday.
Star Wars: The Old Republic is still up and kicking, getting new content all the time and the Story of Knights of the Eternal Empire/Eternal Throne is still pretty damn good. Don't expect it to go away any time soon.
Champions Online is still around for the superhero crowd. Neverwinter is getting a Ravenloft expansion soon. The Secret World Legends JUST launched Season 2. Lord of the Rings Online is still getting expansions all the damn time. That's not including a bunch of other also rans like Wildstar and Guildwars 2.
MMOs aren't dead. They just aren't in the limelight any more. People aren't willing to invest in the large scale ones anymore without a big IP attached and people aren't going to be looking to move to a new MMO until fucking WoW dies.
