So it sounds like they're planning on having sequels at some point, or at least more games with the IP in different genres.
Blizzard has previously hinted they're interested in looking into mobile Overwatch titles as well:

Right now, obviously there’s a lot of character and flavor in the maps and characters, but is there ever a chance that there’s going to be some kind of overworld or PvE content or some other way to engage with the game other than just going into matchmaking and boom, you’re in a match?
Jeff Kaplan: Right now, the focus of Overwatch is entirely on our competitive game. We are very excited that we are going to introduce our play-vs.-A.I. feature, which is getting to be more robust. It’s going to be more like Heroes of the Storm play-vs.-A.I., where players can actually queue up solo but get matchmade with 5 other players and play against bots. I think the idea of exploring PvE in Overwatch as game developers has us all eagerly awaiting the chance to do that, whether that be in some subsequent Overwatch game that we haven’t made yet, or even in a different genre of Overwatch. I think we’re all dying to explore PvE at some point, but not for this game. Not for the initial offering of Overwatch, which is really focused on the team-based hero-action combat. So it’s something we’d like to get to someday in a different game.

It certainly seems to be a meeting of two areas you have some interest. You certainly have a great amount of experience in RTS.
Pearce: It’s definitely something we want to have a conscious evaluation of. If you look at Overwatch and StarCraft, we have multiple franchises that would potentially lend themselves to that concept.
