It is beginning to sound to me like Favreau is a Disneyphile. We saw it in Iron Man 2 with the brilliant Stark Expo scene and the similarities of Howard Stark/Walt Disney.
I love classic Disney stuff, so this movie might actually be pretty good. I wish him best of luck, but it's sad that he isn't finishing the trilogy. It sounds like there wasn't any issue with the studio so I don't understand all the speculation here. Sad though if the reports of an RDJ/Favreau rift are true.
