Yes, it's probably apparent now that Kingdom Hearts 2 Abridged will be returning for a 3rd and final season. Here is the episode listing for season 3:
Episode 1: Roxas Story pt. 1/3
Episode 2: Roxas Story pt. 2/3
Episode 3: Roxas Story pt. 3/3
Episode 5: Atlantica
Episode 6: Beast's Castle
Episode 7: Twilight Town
Episode 8: The World that Never Was pt. 1/2
Episode 9: The World that Never Was pt. 2/2
Episode 10: End.
Note: list may be subject to change.
With this schedule, I'll be ending the series with a total of 36 episodes. I do plan to continue Re:Com at some point, giving that mini-season a total of 6 episodes. I've also been toying around with the concept of making a 10-13 episode Kingdom Hearts One abridged series, then adding all three series into one with a total of 52-55 episodes, 5 seasons.
We'll see what happens,
