Compiled everything he answered, but these are the highlights:
On Stan Lee's final cameo and if he saw the movie:
"Stan loved to wait to see the final movie at the premiere, so unfortunately he did not get to see the finished movie. Stan got a download of the full story the day he came and shot his cameo."
How far is the MCU planned out in advance?
"We usually work with a specific 5 year plan at any given point but often have a general plan that extends much, much further."
About unfilmable storylines:
"Everything is filmable nowadays. It's about finding the most resonant character stories to bring to the big screen."
On if they plan on implementing more about the Ten Rings or the real Mandarin:
"Yes"
Who hasn't been introduced in the MCU that he's itching to introduce:
"You'll know soon enough."
Favorite character that isn't in the MCU yet:
"I never play favorites, but there are many Marvel characters that I've loved for many years that are heading to the MCU soon, but I can't be more specific than that. Sorry!"
When they began planning Infinity War and Endgame to adapt The Infinity Gauntlet:
"We started discussing how to adapt the Infinity Gauntlet comic soon after the release of the first Avengers. It was on one of our creative retreats about 5 years ago that we decided to do it as two films. We started to crack the specifics of the story during production on Civil War with Chris Markus and Stephen McFeely, Joe and Anthony Russo, in a conference room as we went back and forth between takes."
The future of the Hulk:
"Many years ago, Mark came in for a meeting with us at Marvel Studios to discuss ways in which the Hulk could grow and evolve in upcoming films. He pitched a lot of cool ideas, some of which led to what you saw in Thor: Ragnarok, Infinity War and Endgame, and some of which would still be cool to see someday."
