There isn’t a confirmed public date for the next case being added to MM2 right now. The latest info I found says MM2 has not had new working codes in a long time, and current fan/news pages don’t show an announced next case update.

What that means

  • No official release date is posted in the sources I found.
  • Community pages and news posts suggest MM2 updates are discussed, but they don’t confirm a case-drop schedule.
  • A lot of “leak” or “coming soon” talk online is speculative, so it’s best treated cautiously.

Best read on it

If you mean a new item case or content case , the safest answer is: not announced yet.

If you mean codes or freebies , MM2’s code page says there are currently no active working codes, which matches the idea that new additions have been sparse.

Bottom line

At the moment, there’s no verified date for the next MM2 case addition. The most accurate answer is that it’s unknown until the developers announce it.
