I'm gonna hold on to the hope that maybe--just maybe--the nimrods who set up Hasbro's booth somehow didn't put together the Sandperson right. After all, several of the other figures look like they were hastily put-together for the set up, with gaps at their shoulders, elbows, and wrists.
That can't be the way it's supposed to be, because it just looks gay. Maybe there's a way that the bandoliers are removable, and go over the cloth or something. (Realistically, I know that's not possible, with the amount of material there.) They could have even done it like they did the Royal Guard last year, with the plastic arms poking out of the holes in the cloth robes. Or, like Jim mentioned, like the Tusken included with the Bantha--top half plastic, bottom half cloth. They did that with the VOTC Leia and Ben, and they didn't look too bad.
I know the VOTC is all about cloth, and I usually like cloth, too, but only to a certain extent. And this goes way past that extent.
