While I agree with you on the fact that we didn't get to many "new" figures in the OTC. I have to confess that right before the OTC line was annouced I was close to retiring from SW collecting but when I saw the packaging my interest was renewed!..
There has been debate as to the DVD factoring into the OTC line up apparently Hasbro was rushed to create the line since they were planning on a DVD release after the ROTS had been out so there were rushed into creating the line and so we didn't get that many new ones! The Dagobah and Bespin waves had already been announced so those were included in the OTC line.
I can't confirm the DVD rush rumor but it would certainly make sense to me...
Overall I was pleased with the OTC line.
