The FU stuff doesn't interest me much at all, to be quite honest, although I definitely fall on the side of the Stormie purists. I never had a problem with the Clones having different colors according to their legion or rank up until the point that the Empire was established. After that point, I saw the armor becoming the equivalent of the Republic/Imperial Star Destroyers and V-Wing Fighters going from having colored accents to flat gray; for all intents and purposes, the war was over and there was no need for individuality or identification with anything other than the Empire itself.
I'll probably wind up getting the two specialized troopers with all the gear, and maybe Vader just for the "beaten all to hell" look, but everything else (other than 2" Unleashed, which I will buy) will be getting a pass from me.
That said, the second Stormie from the left seems like the Covert Ops Clone Trooper paint scheme for some reason. There's no stupid purple accents (How Covert!
), but otherwise, it has that same kind of look.
