"Return of the Kraang" is it happening or not?

[FredWolfLeonardo]

I really hope it does happen.

As it is, I feel that the Kraang didn't get satisfactory closure (unless you count the implications of the Mutagen Bomb being their last ditch effort), which is a shame because they were one of the show's main villains up there with the Foot, but far greater in scale.

Just think of the possibilites that could be explored, Bishop's history with Subprime, what inspired Kraang Prime in the first place, what the Kraang plan to do with the turtles in retaliation for their failures, what their plans are now at this point, etc. etc.
