I really don't want to go here... but....
(and this pains me to talk about the Muppets popularity in this way)
Unlike the Muppets or Saban's back catalog, Marvel would be big enough for people to notice something was missing if Disney didn't do anything. Especially now, when people love comics (well... half of them do... the rest are poseurs that only like it because it's cool, and just see the movies). Any drop in Spider-Man, X-men, or Iron Man products and/or appearances would make a huge dent. In fact, the news alone must've sent shockwaves out there that are still rippling.
I'm sure Disney would let Marvel run themselves, and I'm sure it's just an acquisition thing... they would be absolutely, insanely, mindlessly stupid to do otherwise. Something I'd expect out of Sony, but not Disney. Look at Pixar. They let Pixar not only run themselves, but Disney's 2-D animation studio.
The main thing I'm concerned with is Boom's Muppet and Pixar comic line. Anyone else think that's a sign of worry?
