From Marvel: "The animated series follows Peter Parker on his way to becoming Spider-Man in the MCU, with a journey unlike we've ever seen and a style that celebrates the character’s early comic book roots. Written by Executive Producer Jeff Trammel."
No voice casting has been announced as of yet. Still an open question whether Tom Holland or Hudson Thames will voice Peter/Spidey. The art style will apparently be very reminiscent of Steve Ditko's early work on the comics.
