I am hoping that you will still be able to do vertex modeling in a separate room as well as the assembly room.  I really prefer to work in a separate and uncluttered area when modeling an object.  Also I would think that it will be pretty slow doing it in the assembly room since the system also has to keep track of all of the other objects in the modeling room.  I always felt that the major strongpoint of Carrara over the other high end packages was the ability to work in separate rooms so you don't get distracted.  And I really don't need more tools cluttering up the assembly room so I hope you can turn them off in there.

Did they do any major bug fixes?  Or are they waiting for 7.0 for those?
