(1989 pages hype, Taylor's Version)
I hate it when people use fomo as an excuse to keep things around. FOMO is literally a problem of the person, not of the product, and those who dedicate time to earning something before it goes away (World 1st for example) deserve to be able to have bragging rights of their dedication & persistence to a product, rather than it being candy given out to everyone because "fomo"
I was right about blizzard's proposed Diablo 4 "expansion" would probably just be a paid new class & new actual content would be done as a free update tied to seasons and not a conventional expansion. If it is going to be more than that then the release panel & the Q&A panel would be two different events at Blizzcon.
Yes it is going over your head.
If they add a new landmass as a .3 patch (similar to how they did with Argus) that exists ON AZEROTH, that is not a part of the "DRAGON ISLES" then it would be canonically a new continent, not a "new world" not a "new zone" not a new anything but "continent" since it's not anywhere near Dragon Isles.
They won't really have to, so long as they don't want each and every zone to be unique and self contained. They might have to change how the maps work though, to give players a better sense of what is going on in adjacent zones.
But just in terms of actual movement, no. The continents are already the right size. It's just the individual zones that are really small compared to what we have.
The world revamp dream will never die!
I think they can use extensively unused Mountain Ridges and Coastal Lines to increase the size without changing the shape of the locations

2 main zone patches will be the new normal from here on out. They likely ran the numbers and saw that not enough people sub in the last year of an expansion for it to be profitable, and "just make better expansions lol" isn't as feasible as just making shorter expansions.
BFA had 4 different raids (actually 4 regular sized raids & 1 mini raid) corresponding to 4 seasons. Legion the tiers didn't correspond to seasons but it had 3 regular sized raids & 2 "mini" raids. I think Shadowlands only had a fated raid because of Covid. And even then, including 10.2, Dragonflight has a lot less raid encounters total than Shadowlands. I think Fated is only something they'd do if something goes seriously wrong in development.

Yeah a .3 patch that was as big as Legion‘s for sure didn’t make much sense financially as that’s the lifetime of an expansion where subs tend to be the lowest anyway (until it rebounds with the pre-patch for the next expansion). So to make a .3 patch so big and huge just doesn’t cut the costs.
Make Alliance Great Again
The patch cadence/meaning of patch numbers was inconsistent across expansions.
6.2 was really the only major patch of WoD because 6.1 added Twitter integration and the SELFIE camera.
9.1 was a disappointing major patch because it added a new zone and new raid, but the zone was pathetically small and bad.
Dragonflight has had 2 zones and multiple world events added before the 10.2 patch.
