Goodman games DCC Mutant Crawl Classics and the DCC Lankmar game. Both based off of DCC but both complete games and different. I think they will be compatible but I'm not sure.
The 3e Freedom City sourcebook is probably the next big book for M&M, but Green Ronin doesn't give release dates until the book is done and at the printer. All of these are supplements though, not new games.YES.
Also The Cosmic Handbook for mutants and Masterminds as a book as well as (probably) their collected Rogues gallery & Atlas of Freedom books.
Conan from Modiphius.
I was moderately interested in the upcoming Sentinels of the Multiverse RPG until I read that it was going to use the Fate Core system, which I have learned game from Fudge. This is mostly an "I only like specialty dice with more (or fewer) sides, and sometimes just as a novelty" thing. Would I have fun with such a system? I don't know. What I do know is I don't want to have to get special system specific dice to find out. I'm much more likely to do my own SotM RPG using systems I already have or learning HERO.
