If you haven't already, check out Stormgate. It's made by some ex-Blizzard devs who worked on SC2, and it just went into closed alpha.
While I would love for SC3 to be great, I'm sure it's a really long way off if it even exists. Stormgate has some very capable and passionate people behind it, and it should release in a reasonable timeframe.
Some ex-Blizzard devs? Try like half of the Starcraft dev team. The other half went to one of Dreamhaven's studios. Blizzard is just kind of creatively dead at this point, they have no imagination, they steal animations and ideas from other games like the whole flying stuff in Dragonflight being stolen from Guild Wars 2, and now they're making a game in the survival genre that hasn't really been popular since the launch of Ark.
