My speculations are:

• There might be an episode involving a musical/ melodic mutant.

• I think there might be an episode that involves a "Groundhog Day"-like concept.

• The Turtles' might get stuck within various video games/ television programs (by the mutant of the week), and April and/or Splinter might have to bail them out.

• There might be a cooking show episode.

• There might be a clip-show episode.

• Leonardo and Mayhem might switch brains for an episode.

• The Turtles' will help various people pick up the trash.

• Michelangelo might sing about making/cooking pizza, while (unknowingly) burning the oven.

• There might be a ninja-training montage for an entire episode.

• There might be an episode involving modern technology (3D printers, holograms, super computers) and the dangers that come from them.

• I might expect lots of cliché stereotypes from certain characters.

• There will be a Q&A episode.

• There will be an episode that has detective work (a.k.a. solving a mystery).

• One of Donatello's battle shells might become corrupted, and he might have it destroyed.

• Mayhem will be missing for an episode. Resultantly, the Turtles' (and probably April) will be searching for him.

Those are my speculations.
