While Blizzard is very much focussed on its big money-makers like its various Warcraft games, from WoW to Hearthstone to Warcraft Rumble, as well as Diablo and the much-maligned Overwatch 2, he's still open to StarCraft making a comeback. That said, RTS fans shouldn't get their hopes up. While the series might return, that doesn't necessarily mean it will be an RTS, and whatever shape it takes will depend on the person or team who goes to bat for it.
"It's not me saying, 'Go make a StarCraft game,'" Ybarra told Bloomberg. "I need to have someone who has the vision and passion that comes with the idea, and I'll bet on that team."
A vision and passion he - according to his own words - clearly does not have. 😑
I think Starcraft has enough story and character development by now that its identity is more than just the mechanics that it started with.
It’s just another game.
It would still be a Starcraft game. If we were to ignore the lore and only consider the RTS format, then even the first Starcraft was "just another game". Those mechanics weren't unique or new.
Similarly, World of Warcraft is still a Warcraft game, even though it's hung on a different framework from the original.
