StarCraft II officially announced

Today Blizzard announced their new and much awaited new project: StarCraft II.

Among the features highlighted, Blizzard mentions new units for the same three races from the previous game, new gameplay mechanics and a new 3D engine.

By the screenshots on the website, I wouldn’t say the graphics are much better than those seen in Warcraft III. To be honest, they just look a polished version of the first game for me.

Would it be that Blizzard is aiming on gameplay rather than graphic gimmicks?
