Among all the weird new confirmation there's also this:
"Trailing after our trip to Kamigawa like a detective with gumption, the following Standard release takes us to the Streets of New Capenna—a city with special significance to Elspeth, built by angels now run by three-color demon crime families.
We'll race through the Streets of New Capenna in the second quarter of 2022."
You know, I sometimes wonder how planeswalkers from very medieval or even primal planes react to jumping to the more technologically/magically advanced ones. I could see someone from Ikoria being overwhelmed by the (superficial) security and vastness of the city of Ravnica, someone from Amonkhet being lost in the prosperous and industrialized Kaladesh and someone from Tarkir having a hard time adapting to the much more subtle (in comparison) urban ways of New Capenna. That's actually something that the story really could get more out of: How being able to experience such extremely novel impressions like whole new worlds would change the planeswalker himself. They somewhat did that with Teyo, but even he seemed to become very blasé about everything pretty quickly (granted, he was thrust into a near apocalypse and had to adapt quickly but still). Other planeswalkers often don't even bat an eye about such things.
Ob Nixilis, who seems to be from a pretty standard medieval plane from what I can gather and was imprisoned on Zendikar (another more primal world) for centuries seems to have no problem adapting to New Capenna, at least judging from the promotional art. I just wish they would do more with the concept. Perhaps they do that with him, I still have my hopes up.
