He hasn't done 2-3 months since before 2020. That's a pipe dream. And, honestly, for ANY developer (with a few exceptions) you should never expect a substantial update in 2-3 months. Maybe 15-30 minutes of play time, but that's the best you should hope for.
Substantial updates should and normally do take at least 4 months, if not 6 or more. And after the first couple of versions (past v0.4 of just about any game) that is usually the going time frame - 4-6+ months for a meaningful update.
For Uberpie, the average is over 6 months, with closer to 8+ in the last several years. ESPECIALLY with this idea to add some new element into the game. Last time he added an element to the game (small chat "sandbox" element), the release date went from Feb 2022 to April 2022 and then needed another release a month later with major bug fixes.
Also he has to cut the content up for Season 2 and then put all the current art through the AI to make it gel with Season 1 art. He lost his head writer, so either someone else will need hired or the current team will need to add that work of revision, additions, etc to the script.
Look at history and then temper your expectations:
