Gametrailers has an interview with Chris Sigaty split into three videos where he describes the differences between Starcraft II and Warcraft III, and find out why the game goes away from a lot of the Warcraft mechanics that had been added in.  The StarEdit tool is much stronger than the Warcraft III WorldEditor.

Sigaty said we will find out more about the Battle.net new features and kinda “Oops” said in the next couple of months, then corrected himself and said in the next few months.  Coincidence that the next couple of months equals Blizzard Worldwide Invitationals? Closed Beta seems to be closer post-Invitationals. – via Starcraft2.hu.
