I recently just got back into collecting disney comics. It’s been years and I’m not sure if IDW still even publishes them anymore? I see new an recent releases by Fantagraphics on Amazon, the new hardcover Disney masters but is any publishing company still releasing single issue comics?
As far as I know no, it's been a good few years since there's been regular floppy traditional Disney Comics. Closest you have right now is Dynamite Comics doing Darkwing Duck comics monthly, which IS fairly close to what new monthly Disney comics would be anyway, as the art is made by Disney Italy artists.
EDIT: also noticed you accidentally posted this in the wrong part of the forum so moved to the right one
Dynamite is also doing some stuff with Gargoyles and Disney Villains, but that's it in the US right now.
They were also publishing Darkwing Duck but just turned that into a Justice Ducks monthly and just solicited a new Lilo and Stitch series. No Scrooge, Mickey, or Donald though.
