Sounds like Mark at RS was told there are 12 more figures planned and will probably be announced/shown at Comic-Con...whee!
I'm surprised it's only going to be 12, and that the rest of what we've already seen through #56 will likely be out by the midpoint of the year. So an additional 12 ROTS figures couldn't take much more than a couple more months to hit retail, leaving a whopping 4 months left in the year for what exactly?
I'm guessing that perhaps Hasbro will switch back to a "Saga" type of line, so it can capitalize on the ROTS excitement and redistribute versions of many of the popular characters from the other 5 films, in addition to a few more ROTS stragglers. I'm sure Hasbro knows that a lot of us are anxious to get back to the bread and butter of the OT soon, so hopefully they'll surprise us and offer some new figures from the originals in the 4th quarter of this year.
I also pray that they revert back to the beautifully styled OTC card design for the next figure sub-line as well!
