Well, the MCU is still continuing after Endgame (even though it may not be as good as the older movies if Captain Marvel becomes the new face of the MCU. Here's to hope that when her character gets tossed between directors, she becomes a more interesting character to watch.)
Gumball already released its last episode.
There are shows in Disney Channel and Cartoon Network to look forward to, though. I'm actually really excited for the Owl House, Amphibia and Infinity Train.
