Update: There's an explanation of how this is going to actually work here.
Blizzard's announced that StarCraft II is, in fact, a trilogy, and will be split into three stand-alone products.
The news comes out of BlizzCon 08, which opened last night just as we were descending into our post-TGS coma.
The first game in the series will be Terran: Wings of Liberty, followed by Zerg: Heart of Swarm and Protoss: Legend of the Void.
Details on pricing and dates are unknown.
Each game will feature 26-30 single-player missions and multiplayer upgrades over the previous disc.
We'll have more on this as we go through the morning's new list.
