Just cause it's Disney/Marvel doesn't mean they threw a bag of money at them. It doesn't look like they did. There's a reason that with such a small roster that there are so many recycled characters and animations from UMVC3. I guarantee you the budget for this game was nowhere close to the budget for Injustice 2.
Yeah it kinda does. Companies that big have to invest just not in the quality of attached products, but the protection and fidelity of their brand. After the success and longevity of MvC2 and 3, its ridiculous to assert that Marvel and Disney would somehow NOT support that venture. Also, not supporting this game would serve to damage their other interests when it comes to the Esports scene, licensing markets, and other potential ventures still not on the board.
short version - underfunding this from Marvel's side is a ridiculous assumption based on nothing and it goes against like..... all trends lol
Also, as much as I can't stand NR.... put it like this, people can critique their pre-release designs and not only does a face get fixed (black canary) but animations across the board are smoothed over. Its easy for them. Capcom is making this hard because they're simply having a lot of internal trouble. Everything about this game has looked off since the first leaks.
