a) Changes to the rules and design of the game can take longer than one week or two. These decisions require thought and a lot of discussions within the Larian team.
b) Beyond the fluffy funny introduction to the update, this update focuses mostly on crashes and bug fixing, and new passes on the cut-scenes (which they will do every EA update really). Which is understandable. Also see point A.
I am *not* saying the core systems are good at the moment --for example the party/character movement out of combat is annoying as hell and I suffered it for over 100 hours in DOS1 already-- but changes to the design, rules and engine will take more than a few weeks.
