>>8481883They have only said that there are 7 waves planned so far (they're up to halfway through 2022), with 4 figures a wave every 4 months.
Which means there are at least 16 more toys currently planned. We have Donatello and Usagi Yojimbo confirmed to be coming out by name (Preorders for Donnie in October, Usagi sometime in 2021).
Krang is a major villain and an iconic character, he's guaranteed to get a figure. (And Casey Jones is also a guarantee since one of the main company guys mentioned Casey as one of his favorite characters.)
Most of the debate in these threads is if Super7's Krang toy will be the bubble walker, the original vehicle sized android body, or the much later release of the half-sized android body. We don't know yet, and Super7 hasn't hinted yet. Considering Krang is however big he feels like being thanks to the magic grow/shrink chip he had Shredder install into the android, technically any size is fair game anyway.
If we don't find out next week, we'll be wondering until January or so.
Vehicles are a possibility but have not been mentioned at all. The closest we've gotten is that they're planning two more very large playsets after the He-Man one they're doing, which, as a pure guess from your friendly anon, would indicate a thundercats playset for that line, and a turtles playset for the tmnt line.
