I'm gearing up for a bitch-fest on the Padme if she's pre-posed, but not the droids (well, not yet anyway). I love the concept of a de-cloaking chameleon droid like that... Kind of like Predator.
And speaking of Predator, I got the Alien Vs. Predator Snap Kit figures from Hot Toys, and one of the Preds is a cloaked "clear plastic" figure. It's sort of cheesey (no cheesier than a holographic figure though or a spirit figure), but at the same time the effect turned out cool too... It makes a neat variation of the toy, and fits in cool like he's stalking someone in the Cantina or something. So the idea of the Chameleon Droid de-cloaking is neat. I wish they'd make a completely "cloaked" one though and release it with a completely uncloaked one then at some point for the droid army builders. A "clear" one would be a neat one though I think.
