I just think that the animated style line has run it's course and while I'd love to see Pong Krell at some point, I find it highly more likely that they'll make a Pong Krell with parts that could also double for an update of Dexter Jetster so they can get two figures out of one sculpting effort.
This was my argument back when they announced a separate style line in the first place - in the long run it would bite them in the ass that they weren't trying to get the most out of existing tooling to get the line going and then as the line progressed, being able to add to the "parts library" for piecing together other figures.
I think Krell has already been sculpted in the animated style, and this has been done for awhile. It seems unlikely they would tease something in a Q&A that was not already pretty far down the line in terms of development. I just don't think they have a viable way to release him right now. To your point though, I don't know why they still couldn't mix and match some animated/realistic parts going forward, it's mainly the faces, forearms and lower legs that differ. That would definitely help them get more mileage out of existing work.
Honestly, I think it's Hasbro's committment to the animated line that has run its course. I feel there it still a lot of great potential in this line if they would only recognize it. New animated figures still sell briskly. How many pegwarming Commander Foxes do we really see out there, y'know?
As far as the show, there's definitely going to be at least one more season. I think the future gets cloudy after that, no matter where it airs, because then you're starting to get closer to Episode 7 and the suits probably would not want the show airing when the new movies are rolling out. Hope I'm wrong on that though.
