Karune made a clarification about certain Starcraft II System Specs details that are circulating the web after a Spanish Magazine published them.

Karune: “Many fan sites are mirroring an article published by a Spanish Magazine called Micromania. To clarify, all system specifications made in that article are only speculations and are not official system specification for StarCraft II at all.

Like all Blizzard games, we aim to have a vast majority of PC owners to be able to run StarCraft II, but there are no official optimal or minimum specifications for the game at this time.”—Source: Battle.net
