-You're going to need a source on a third StarCraft game. And no, Ares doesn't count.

-I wouldn't count on an SC3 for a long time, if ever. Even discounting RTS being a niche genre, SC1 and SC2 are still being updated. That, and with WC3: Reforged a thing, I can't see Blizz pursuing SC3. That's not to say that more SC games won't happen, but I doubt they'll be RTS ones.

-There's not much point with a broodmother OC, when Zagara and Niadra already have an adversarial dynamic. Similarly, Colin is a bit of a non-entity. He's pretty obscure, and not someone you'd headline a game with. Not unless something like "StarCraft: Shadowguard" was made in the vein of what Ghost might have been.

-If you're talking about plot, I'll say it before and I'll say it again, there was no reason to continue the story beyond LotV. Still, the genie's out of the bag, so if we look at everything that's happened since then, here's the main plot points that have come up:

a) The UED

b) The breakdown of relations between the K-sector's powers (see Shadow Wars), including Zagara and Niadra apparently being at odds over the future of the zerg (again, see Shadow Wars)

c) The Umojan Protectorate is asserting itself and preparing for war with the Dominion (see the skins)

d) ...whatever the heck Sacred Land is hinting at with the idea of Stetmann spreading "congregations"

e) The Ihan-rii (seriously, you can't NOT address them at this point since their mere presence is a game changer)

Looking at these trends, they're marked primarily by the existence of new powers and the emergence of intercine strife both within and between factions. So, assuming that these plot points aren't addressed in the EU, then a hypothetical SC3 could levy them.
