outlined last month for Starcraft 2 will be implemented this coming Tuesday, September 21, when Blizzard updates the successful strategy title to version 1.1. These new features include support for NVIDIA 3D Vision displays, left-handed hotkey options and new map editor functionality. The full list of features and balance changes can be read over on Battle.net.
The patch will go live during a maintenance period starting Tuesday morning at 5 a.m. until 11 a.m. PDT, at which time the game's online multiplayer modes will be temporarily offline. If you've got a score to settle with a distant rival, you probably shouldn't schedule your grudge match during that downtime.
