I was sort of speculating that with some folks recently, that Clone Wars may be getting some realistics in an attempt to move away from animated completely and meld everything into one line (possibly looking at the line's eventual end with the cartoon's eventual end). That's fine by me.
I will say though, I can't agree on the "secondary" characters selling well with Clone Wars... I think, if anything, Hasbro's proven that they don't do well.
Embo, Cato Parasitti, Worm Loathsome, Adm. Yularren... They all did poorly. Embo was hard to find for about a month, then he's everywhere. If it wasn't shorted at retail, it wasn't hard to find (IE: Jar Jar, or Onaka, etc.). Right now Seripas is still relatively new, and hasn't exactly shipped in good quantity. I've yet to EVER see one on the pegs, but I've also yet to see a glut of any of the last couple waves either. Ship enough, and he'll pegwarm too. Same with armored Savage, though I consider him a little more of a main guy since he has that whole Maul thing going on, and kids love Maul or anything Maul-Like it seems. But still, Shirtless Savage... Very easy to find at retail, and do kids really give a poop about him having a shirt or not?
If anything I think CW has shown that kids do NOT care about the lower level characters though, and that collectors don't support CW enough to warrant heavy investment in the more obscure. Just my opinion though.
I think they still could do more figures for the line next year, as has been pointed out with just doing repaints and part swapping, and minor retooling. Clones could just get new gear and I think they would still do ok. Droids could get changes and not do too badly.
