If Disney is smart (and it usually is, compared to certain other companies) they'll learn the huge mistake CN made by ticking Genndy Tartikofsky off with what they did to Sim-Biotic Titan. Sure, they can give PPG and Samurai Jack licenses to IDW, but they're never getting Genndy back. And considering his first flick at Sony, Hotel Transylvania, made an unprecedented amount of money, I've no doubt they realized what they did was absolutely idiotic.
If Disney wants to tick off Craig McCracken, they do so with an insane amount of foolishness. Seriously, I loved Foster's Home and all, but I feel that Wander over Yonder is the true follow up to PPG. As for GF, I think Disney knows it has a cult following. I saw a LOT of Dippers and Wendy's at the convention I went to in May, not to mention a LOT of Artist Alley GF artworks. It even got a DVD release. A crummy kiddy one, but that's more you can say about Fish Hooks.
