There's finally (probably) some construction on the "new for 2023" Avengers ride which changed into a Spiderman Tower of Terror ride.
Behold the crane!
There's also this quite large building going up in the space between Toy Story Land and Frozen Land. There used to be some temporary buildings on the site, but looking at Google Maps, they must've been cleared a while ago and this new one is going up.
I'm assuming it must be for the new Pixar/Monster's Inc show, which seems to be some kind up upgraded "Tough to be a Bug" type attraction. From Time Out:
"The new Pixar adventure will be an immersive theatrical show centred on the world of
Monsters, Inc. that promises to be fun, heartwarming, and ‘unlike anything ever done before at Hong Kong Disneyland’. According to the park, the experience will utilise cutting-edge theatrical technology that blends real and digital environments, so our best guess is it might be something similar to the ‘It’s Tough to Be a Bug’ show at Disney World’s Animal Kingdom (which closed to make way for a
Zootopia attraction in March this year, RIP!) or the ‘Muppet*Vision 3D’ show in Disney World’s Hollywood Studios (which also finished its run permanently earlier this year in June after over 30 years) – but likely with less animatronics and updated animation style."
The plot of land is pretty big, so I hope that this is not the only thing they're going to do with it. The black and red gate in the last picture (next to Barrel of Fun on the Google Map) leads to an access road. Frozen has a similar gate (next to the fountain/ice cream place), so I'm guessing these could be used as access points to the new Monster's Inc attraction (whole Pixar land?) as well as a faster way to connect those areas by bypassing Fantasyland.
