As for this? I think that Hasbro is simply referencing the source material, rather than realistic VS animated style figures.
I agree with you there. Lots of the 5POA characters revealed are from the prequels AND TCW (Mace, Obi-Wan, Anakin, Yoda, Clones and Droids) so it makes sense that Hasbro would highlight the cross appeal. I suppose it is possible that some Clone Wars-only characters will make it out, as they did have a placeholder Rex figure on display. I'm guessing any TCW characters in the line will be limited to 5POA, and might be a less-animated (if not realistic) style.
