The full line-up of Marvel films through 2019.
EDIT: Damn, it’s fan made. I was so excited too. I will stab a bitch for an Inhumans movie.

"Actors John Boyega, Daisy Ridley, Adam Driver, Oscar Isaac, Andy Serkis, Domhnall Gleeson, and Max von Sydow will join the original stars of the saga, Harrison Ford, Carrie Fisher, Mark Hamill, Anthony Daniels, Peter Mayhew, and Kenny Baker in the new film."
Well, there are anthologies like Trick r Treat, Creepshow, Tales from the Crypt, V/H/S and the ABCs of Death that you might enjoy. Those aren’t shorts, per se, but if you like shorter-form stuff, check them out.
As for true horror shorts, one of my favorites is The Cat With Hands. It’s creepy and cool and pretty and spooky all at once. There are a few great horror channels on youtube, like Daywalt, that are doing horror shorts frequently. Below is a big list of more. I’m going to include links to the shorts you mentioned, for anyone who hasn’t yet seen them.
