[ubuntu-art] how far for Hardy

[SzerencseFia]

One question came in my mind. (it is probably for kwii)
How far are we going in the change of the Ubuntu design? I mean is there 
any limitation or border what the community is not going to step over in 
the change of the design?
For instance if there is an idea about change/separate of Metacity 
buttons to the sides would that be to much and out of the way?
In other words what part of the current Ubuntu design is going to be 
kept having slight or no change at all?
