Well, I don't like action features, but at this point to me at least all signs do point to an improvement over the EP2 action features.
I never did mind the action features that the Dooku figures had - in fact, I thought those ones were cool.
Here's what I think about these figures -
Tion - very cool
R2 unit - done before, but nice addition for astromech variety
Obi Wan - not too bad, but the shoulders look out of whack, kind of like the POTJ Quit Gon
Mace - looks like the absolute best Mace Windu figure ever
I say bring 'em on!!
