Changes

There was no mechanism in the [[BlizzCon 2008]] or [[BlizzCon 2009]] demo builds to ''travel between checkpoints'', (there were no waypoints in the build either), but the D3 Team has talked [http://www.diii.net/blog/comments/diiinet-jay-wilson-video-interview] about allowing players to resume a new game at the last checkpoint reached if they wish it.
