I know it sounds premature to say this without much info on The Good Dinosaur yet, but I feel like Inside Out should be the film Pixar really pushes to its success. I have a sinking feeling that all the production craziness on TGD may end up hampering the final product, and even if it doesn't, Inside Out is already building up a ton of good will.
Again, we need to see how the cards fall, but I think Pixar is going to play IO before TGD in this race.
