It's funny, I also got that impression that they're essentially just waiting on relentlessly for the show to end. They've already made clear that the line will transition over to the realistic style. Honestly I love the realistic figures we're getting soon, and it'll bring something fresh to the table to keep the realistic line going on without getting stale in character choices. Think about, all the new characters from TCW that we can finally have now. I wouldn't be surprised if we even get a Duchess Satine waaaaay down the line.
The problem with that is, it won't look anything LIKE the actual character from the show. You can't render a 3D animated image into a realistic style without losing the unique qualities of that original image. And whoever sculpts heads for Hasbro really struggles with female likenesses IMO. So we'd end up with some cruddy looking thing that is like the BP Talzin figure, not really animated and not really realistic either, but a crude mash-up that ends up bearing little resemblance to the source material.
Well, that is just my opinion anyway. I know there is love out there for the realistic cartoon stuff but I can't help but regard them as atrocious.
I think it would be hilarious if the show somehow had a HUGE surge in popularity and ended up running several more seasons, and kids even started buying the figures again. Then they'd pretty much HAVE to commit more resources to it, begrudgingly or not.
