I know you're being sarcastic, but Mickey & Minnie's Runaway Railway at Hollywood Studios opened recently. It's really well done. There's also a new uber-stylized show called The Wonderful World of Mickey Mouse on Disney+.
(That being said, there's never really been much Mickey media. This is the first ride featuring him, and he's never had his own full-length movie. Mickey is way closer to a trademark, in my opinion, and has always been that way.)
Fun fact: the guy who plays the Tres Commas VC in Silicon Valley is the current voice of Mickey Mouse.
