Yeah, after thinking on it overnight, it doesn't line up from the Universal side of things in regards to them losing Marvel. There's nothing from anyone credible that even remotely points to MSHI going anytime soon, nor would it be in the best interest of Universal to prioritize a MSHI replacement.
While it's a fun theory to speculate on, this isn't the place for it, and it's best to move on from it at this point in time unless trustworthy people on either here or Magic start pointing towards a scenario like this.
When it comes to AC, the only things of substance at this point in this is, according to insiders with a solid track record on Magic:
•Disney apparently has plans to announce what's going into Animation Courtyard the weeks surrounding the opening of EU
•It's apparently not Simpsons or Zootopia.
Apologies for jumping the gun on the DC assumptions, I had a rough night last night and thought I put a puzzle together.
