Forgive a little soapboxing, but I think a lot of this worry/hurt comes from the fact that Disney has all but given up on the Muppets. This is the second longest drought without a Muppet movie and there has been no major TV special or theme park project to back them up. Muppet Haunted Mansion & Mayhem were both great but barely anyone knew about their existence. California's MuppetVision disappeared in 2014, there is barely any merch produced by Disney themselves, and as mentioned before they can't even be bothered to get Muppets Take Manhattan on Disney Plus. Little things like third-party produced action figures & board games and Waldos getting replaced by projections are the biggest news we Muppet fans have. The fact that operations are so keen to cut entertainment these days and additions have been extremely few and far between (barring next year's Electrical Parade!!) means a live show is all but unthinkable.
In 2009, there was a large Muppets presentation at D23 in which various major projects were announced. Despite the fact that the majority did not come to fruition, this was a great time of hope for us. This year, we got a huge Avatar pavilion - even though Disney does not fully own the rights to the property - and Eric Jacobson wasn't even at the Miss Piggy panel.
Maybe most of the public has moved on - there are certainly folks on this forum who are not fans of the Muppets. But it is rather disheartening and difficult to accept that Iger & co. just don't want to throw the same amount of effort behind the Muppets as they do Star Wars, Marvel, Cars, Encanto, Moana, Monsters etc. because they weren't grand slams at the box office/Disney+. At least for their first 30 years of existence and that brief blip around the Jason Segel movie, the Muppets left an indelible, unique mark on the public. Monsters Inc. has always deserved better than just Laugh Floor and a Sulley meet, but the Muppets deserve better than nothing.
