I'd only do the Bossk and Tarkin begrudgingly for my figure focus... I personally hate the 6" line's direction of a new scale... Like all things separate of the main realistic 3.75" line, I see it as largely taking resources and wasting them.
I appreciated Clone Wars when it was popular and hot because that returned money into the line, but I see things like Choppers, the new 12" roto-cast things, and these 6" figures as just an ultimate drain on a line's resources that won't work long-term. Fortunately 6" is limited, for now, but I don't imagine it will be forever if it gains even the most remote traction.
