Russos carefully answer 3 questions in this vid (nothing earthshaking) - don't know how to link to this directly.

I waz a bit sorry to hear of Thor being of interest to Anthony Russo story-wise. I like Thor just fine, but saw plenty of him in Ragnarok and bein' king now just don't see any trajectories that can't be predicted - more or less. Be nice if his hair was growing. Tho who knows, maybe there is a push to fuss over Thor now after Ragnarok.
But IMO Ragnarok isn't anything like the IW I am hoping for e.g. enough with the comedies (not that I didn't love Ragnarok - GOTG2 not so much and that one IMO wasn't funny anyway.)
For me I just wanna know about Team Cap
; I feel like I've seen plenty of everyone else and WS & co. are my favs anyway. Although it's possible from the vid comments Cap, IM, and even WS (maybe)? and whoever else may not be long for this world.
Just idle speculation from the comments re stakes, "sacrifice" etc.
That said, the comics are like revolving doors; also interesting about Joe Russo talking about having a "good story" no matter what happens. Which I had figured before TLJ 'coz it's the Russos, but LOL I bet the MCU was paying a lot of attention to the complaints about TLJ. Where some felt that a good story was NOT told, especially about a beloved hero (Luke).
