I got a chance to listen to the Collectorcast on the way to work today as well, pretty good info there. I'm interested to see the Movie Heroes line, just to see what it is, and it also sounds like there will be a pretty good amount of reveals at NYCC.
As far as CW, from what I gathered Derryl made it sound like it would continue to be kid-focused and "core character" oriented. He also said that next year would be even more focused than this one, so it sounds like figures like Seripas will really just be a here and there thing from now on. Probably similar to this year, or maybe even a little more streamlined. They did actually ask about the Nightsisters as well, and it didn't sound real likely (although they mentioned possibly as a realistic figure in the vintage line).
He did mention vintage through 2012, but wouldn't confirm anything for 2013. Not that it means anything, as he said they are just planning that year now, but he did mention that eventually it may get a rest so they can bring it back again later without it getting stale (or something like that). Definitely looking forward to NYCC though, and curious to see what next year will offer. It sounds like these next few (six?) years will really be focused on the 3D release of the year.
