The most popular, recently released RTS I can think of is Factorio. It seems like RTS game elements have been splitting into their constituent parts and forming a game around those.(e.g. production to Factorio, or combat to DOTA) It may be that way there’s a greater ROI on smaller/simpler games than building out all the components involved in an RTS game.

Today gamers don't like to multi-task and Starcraft(and its clones) is a multi-tasking monster(scouting,economy, building, combat), so similar RTS which force multiple issues at same time are outfoxed by simpler game mechanic games where attention is more deeply focused and players can gain skills easier. Another factor is RTS are anti-casual, they don't forgive mistakes and only a tiny % of gamers can handle the stress of constant losing/failing, in context of highly demanding, multitasking heavy game. The genre doesn't accept game style variations either - a single cookie-cutter build order is the best one, the rest is suboptimal and loses you either time or money.
