User blog comment:GoldMan27/The Official Detentionaire: Season 5 News Blog/@comment-101.174.17.28-20140302231401

Got something (although not from the most reliable source). I was looking at the list of Detentionaire episodes on Wikipedia and a note attached to Date of Destiny said:

Note: The ratings of the episode will determine whether a final fifth season should be made.

That's gotta mean something, right?
