What is an "Enchousen situation"? I came across this phrase in this r/Gintama thread about the Porori Arc mentioned in a "new season" announcement. The original poster said:


  Now this could STILL turn out to be an Enchousen situation, which I am hoping, but for now all we know is that we'll be getting a pool episode rerun.


A commenter also said:


  im sure its an enchousen situation
  at least i hope!


What is an Enchousen situation?
At that time, it was still not clear exactly how many new episodes will be in the Porori Arc and I believe they are just referring to the possibility of Porori Arc being a full cour of Gintama like the Enchousen instead of just a couple of extras like Aizome Kaori.
