I would say it would be an engine for a new RTS game, seeing as Starcraft II has come to its end of the story (unless they try to revive it, please don't). Warcraft 4 would be nice but definitely not happening as they're focused on WoW now, so I'm probably expecting a new story to be coming out...
A sandbox game is a genre Blizzard has yet to explore, but it's not going to happen. Sandbox / Survival / Crafting / Early Access - The 4 horsemen of the apocalypse that travel across steam, Blizzard will be avoiding this, plus a sandbox is way too much work anyway for next to no profit

Warcraft 4 plsssssssssssssssssssssssssssssssssssssssssssssssss
If, and I doubt they are, but if they were to make something new my gamble would be on a Zelda clone and somehow jam online connection into it.
Man, if Overwatch would've came out as the Titan MMO....

Maybe the void is all the same in Starcraft and Warcraft and they will meet.
Starcraft + Warcraft = Star Wars?

Let's see. It will be named Random Casual Multiplayer-Only Some Kind of MOBA Game.
Come on, guys, Blizzard no longer makes quality games, they're all just multiplayer crap that you get bored after 20 min. With the exception of WoW, of course, but even WoW is shit right now.
a blizzard (capcom vs street fighter like) fighter game would be interesting, and its the only thing blizz has never really touched, we also know that there is a diablo product being developed atm, but have zero details on it.
