Here's stuff from one of the artists on Battlefield 1. So yes, there is heavy bulky plate armor like that around the 1920s. It's not used as much, but it's there. Also, Keith Baker has made blog posts detailing Eberron fashion, and how people could wear heavy armor that doesn't look like...
It also helps that, after Eberron came out in 2004, other settings became more and more dungeonpunk, so Eberron would probably have to distinguish itself even further, if the early artwork's accurate.
Curse of Strahd and the Lost Mines of Phandelver come to mind. I know people that are running (and I'm in one of these campaigns) or planning to run the former; the latter has received awards and a revision/expansion.
I would quote this part right here.
"While we don’t really know how that’s affected the head count at Wizards, it’s clear from the 2025 schedule that the pace of releases is off. There just aren’t as many books coming out this year as I was expecting."
That is still more than one release in the year. Tiamat books between corebooks aside, it took four months for another to be released. The 2014 DMG was released December of 2014. Princes of the Apocalypse was released in April of 2015.
That opinion article has gotten a lot wrong. One D&D's a name for the playtest phase. The OGL debacle has been resolved with a lot of people happy. Also, nothing after the Monster Manual this year? Really? We get two Forgotten Realms books, a dragon adventure anthology, and a remake of Keep on...
