Crazy eh?! I knew a few people thought SDCC might bring such an announcement, but I was all "nah, they'd never do that". Happy to be proven wrong! Going to go back to the start and re-watch them all now.
So, 12 episodes. Even if they are only the standard 20-22min long (although, theoretically they are no longer constrained, being on a streaming service), that's 4 hours, or the equivalent of 2 feature films. Very decent amount of content.
