CollectionStation had an opportunity to ask Hasbro questions and officially get a reply. Here they are:

CollectionStation.com: Last year, Hasbro released the R2-KT figure while making a charitable donation to ensure that the spirit of a figure for the Katie Johnson charity was fully met before any were sold. With R2-KT appearing in the Clone Wars movie, is there a chance we could get animated R2-KT as a repainted animated R2-D2 figure in a similar charity-type release?
Hasbro: We do not have plans at this time, but there is a strong possibility that we could revisit that promotion in the future, perhaps in 2010.

CollectionStation.com: Will there be more droid repaints in the Clone Wars line? The molds already exist, so they shouldn't be too difficult to achieve. For instance, will there be TC-70 based on the C-3PO mold, R4-P17 based on the R2-D2 mold, or KRONOS-327 based on the IG-86 mold? TC-70 obviously would be a good companion piece to the upcoming animated Jabba you're developing, and Obi-Wan needs a droid to fit in his Jedi Starfighter's droid slot.
Hasbro: Two of three droids you cite will be out within a year. The remaining one has a strong likelihood of also coming out, perhaps as an exclusive at some point. Stay tuned!

CollectionStation.com: In Hasbro's GI Joe line's comic packs, they have moved beyond mere reprints to also feature entirely new stand-alone comics. Given that Dark Horse has released similar Star Wars comics to retailers in the past, have you considered working with them to commission new stand-alone Star Wars comics that feature highly-requested EU characters that otherwise don't appear in the comics and therefore have a lot less chance of being released as figures?
Hasbro: Creating new comics comes at a not-insignificant cost, and we prefer to keep our investment in the new figure tools rather than new untold comic stories. The reason we were interested in partnering with Dark Horse was the rich treasure trove of comics that have been produced over the 30-year run. That's not to say we eventually won't do custom comics (Dark Horse is very keen in working with us on this), but the reprints is where we plan to keep our focus.
