Also, I've been looking into that "Frontier" thing a bit more. Turns out it's just the name of one of the models, not necessarily the entire kit/related models. Currently connecting the models together to see what truly belongs to that "kit". Right now it appears to be pretty old, predating most of Dragonflight's other models/development. It might have been part of a Dragonflight intro experience/playtest very early on and got scrapped (hence why they're unfinished and untouched since 10.0.0), but further investigation is needed.

I am still expecting a 10.1.7 PTR build this week, although it's probably content locked at this point.

Honestly, it's better to "speculate" on the lore and content of the patches than the "dates". It's just semantics and trying to find patterns. I did all the math already, and clearly it means nothing. So, clearly they don't have a "pattern" for announcing content, it was just an anomoly. However, I think a 10.1.7 cinematic is still certainly in the cards for the week.
Best thing to do is just focus on the lore/future content. Then, when news drops, we can talk about it, instead of hyper focusing on the "when" which is clearly not worth the stress.

It's honestly crazy to me how close we are to encrypted story content in 10.1.7, 10.2 news, Blizzcon, etc. So exciting!

I'm conflicted, personally. I have "no expectations/hopes" for 11.0. I've always been of the mindset that Blizzard could literally announce anything for a new expansion and I'll eat it up lol.

You don’t need to respond to everything. Just apply some humility and move on.
Either way, we’re going to get news when we get news. Not the end of the world that we haven’t gotten anything, and when it does come it will be nice.
Hype can still accumulate in lieu of this.

So far, seven versions of WoW were placed on Azeroth, and only three outside of it. Whenever the expansions takes place outside of Azeroth, people want to go back. At the same time, space on a world map is limited and Blizz is running out of islands big enough to facilitate their own expac. I would expect, that with the backside of Azeroth Blizz wants to make more space and lore to be explored without leaving the planet. The question is - would a small island, regular expac style, be sufficient? Or do we need something more substantial? A new continent, with half of it hidden with magic, so that things can be added to it later? A big new continent added all at once (not likely)? Or maybe, Warcraft 4 expanding the lore behind the backside of Azeroth to familiarize us with zones that could later be introduced to WoW?
Ohhhh, how amazing would it be if they were to announce Warcraft 4 along the next WoW expansion? It would be a really good way to introduce The Other Side of Azeroth and Avaloren (I am guessing that they are at least two different continents), so that we actually care about what is happening there.
BTW, again, no news today. I am guessing that we will not get anything until next week. It is really frustrating but at the same time, when 10.2 is announced, we will have something new and shiny to look at right until Blizzcon.
Good times ahead of us indeed.
Do not take life too seriously. You will never get out of it alive.
The thing is that of the three times that we have been out of Azeroth, two have been absolutely disastrous (WoD and SL), especially lore-wise.
I am not against the cosmic theme, but I think that the Legion approach works better for now (a patch centered in another planet / plane / dimension / cosmic stuff). Keep building the cosmic theme until there is actually a lore reason to go out of Azeroth, and make people excited about it. Another cosmic trip in which Blizzard pull from its ass another SL which inhabitants are suddenly responsible for everything that has happened since the beginning of time, and WoW's lore would not be able to recover from it. Hell, it has not recover from SL yet.
Chris Metzen is there again so hopefully things will be alright.

I kinda want a mini revamp
A handful of zones with more redone each patch
Plus side is the ones who scream for a 100% revamp will say it's awful but still play

I believe Chris Metzen can still fix things because even when we had the first two "filler" expansions (Warlords/Pandaria), he managed to make it cohesive at the same time that both expansions felt like a proper progression of events.
Although I agree that Warlords was a bad expansion in general, it was mostly due to a lack of content, the lore was acceptable if we ignore the damage caused by the alternate time/travel time plot holes.
Metzen left in Legion, and the lore took a massive nosedive as soon BFA pre-patch events started.
It could be a coincidence? For sure! But I think it's not.
I don't think leaving Azeroth to explore other planets is a bad thing; this rule only applies to Cosmic planes such as Shadow/Void/Life/Order/ETC-lands, where they change the established rules and lore to create stuff out of the blue.
For instance, I still think that the Argus plot not being covered in a fully-fledged expansion was a mistake.
