I think with Strobo it's two things, the bonus Zodak head and the fact that it sold out so quickly, leading to panic, a scalper's dream. There is no doubt in my mind they just put a few online to see how it would do because really, this character is pretty lame and minor. But people need to have it now so they will pay. A fool and his money and all that. He will be online again, most likely they will have tons of him around Black Friday.
I will not be shocked if this is the last year for the MOTUC line. It gets more expensive every year, there are not too many characters people want and people just seem to get more and more upset by how the line is handled.
