Just minutes ago, at the Worldwide Invitational in Seoul South Korea, Blizzard Entertainment announced Starcraft 2. SC2 is going to be an RTS, with some of the old units using new abilities, as well as newly created units.

* Protoss can create force fields anywhere, and phase fields that teleport units to anywhere on the battlefield.
* Zerglings can mutate into incredibly powerful, moving bombs.
* New Protoss unit: Immortals; They have a special shield that activates when being powerfully attacked.
* New Protoss unit: Stalker; Is a quadroped type creature that has a blink ability.
* New Terran unit: Reapers; They can hop across uneven terrain using jump packs, and seem to be the counter to Immortals, with two pistols that don't activate the Immortal's shield.
* New Protoss unit: Colossus; Has dual laser weapons and very long legs, allowing them to traverse difficult terrain.
* New Protoss unit: Phoenix; Can charge weapons for multiple blasts, but once charge is used, ship is left inert for a short period.
* New Protoss unit: Warprey; Flying unit that does increasingly higher damage the longer its laser hits a target.

More info coming as soon as it's available.
