Ok, so the top theories of where we're heading to for 7.0+ would be either Meracydia or the Void/other shards. With 6.1 we got some mention of Meracydia and especially with the Void. (Seriously Y'shtola was starting to freak me out with how obsessed she was over this)
While I know that it's still far too early to be sure, but where are we going to head to next? I can't see how the story will be connecting us to Meracydia just yet, and I feel that the New World is still too early and we've heard barely anything about tit. But I don't see how we can go to the Void when it is just an empty void. The reason they could make the First work was because they still had that one continent with actual people surviving on it. Despite that it was in a dying land, they still had different environments and zones for us to visit... just enough that we had a whole story and they were able to add onto that with the Eden storyline.
But the void... there's nothing left of it but empty darkness and surrounded by void sent. I don't see how we can honestly have an entire expansion about it. Now, granted I think that it would be awesome and would love the chance to be able to go there if they could make it work... but unless some kind of city did manage to survive there or so many centuries... I don't see how we could have an entire expansion of the void. I was thinking that maybe the Void could be like the new Eureka or Bozja... but I thought that Corvos seemed more likely for that for Endwalker. Then I thought that while exploring parts of the 13th, the Golbez look-alike escaped with the fiends and settled down in Meracydia and we have to go after them. And the entire 7.0 expansion could be us fighting him and at the last we send him back to the Void where we learn the fate of Azdaja? But I honestly don't think that the archfiends would survive that long, I do think they are being set up for the new trial fights in 6.2 and onwards.
Sorry, I know my thoughts are all over the place, but what do you think? Are we going to the Void or Meracydia... or maybe someplace new?
