>I just hope all his properties go to the public domain already
Probably not gonna happen. Disney will spend their last money, take on even more debt, or sell of bunch of other newer IPs at a loss, just get enough lobbying money to secure their Mickey Mouse and other related IPs. It will take years before people will start travel en masse like they used to and have enough disposable income again to visit parks. Until then, socks with Mickey Mouse and other similar merchandise will be Disney's lifeline.
It might not even be Disney who gets the new extension passed. By 2035, Batman, Superman, and the first Looney Tunes will be entering public domain too. It is not likely that the Warner Bros will let any of them go. My bet is that they will band together with Disney and some sort of extension will be passed by the end of 2023. However, it probably won't be as easy as it was back in 1998. Google, EFF, Public Knowledge, and multiple other entities are against copyright extensions so there will be resistance.
I searched for it, but there is nothing known so far. Disney still has 3.5 years to wrap it up.
