They announced SoTMG last year. I very much doubt we’re getting a big content release tomorrow, but expect to at least learn what’s coming in the next seasonal update.
Edit: and looking thru the big ol hotfix code updates, we’re getting what looks like a new event with an insignia as a reward for skulls. So, better than last year at least! There are a ton of edits in the code…nothing I’m 100% certain on, but I do find it interesting that they’re touching the character select screen for the first time in months!
