I assume patch 7.1 will be dealing with King mini-Ja and how he hates being King in Solution 9, so Wuk Lamat is almost definitely going to be there too. Outside of that I guess it depends where they go with the story- the only other hints we have for what content is coming are:
-Funny dimension hopping hourglass
-Erenville investigating the anxious animals in Shaaloni
-FF11 crossover
-Bermuda Triangle exploration zone (probably relic)
Assuming the hourglass is the main MSQ point, I'm more leaning towards Erenville's stuff being side content (maybe they'll bring the trials questline back this time since all trials were MSQ in EW) which leaves Wuk Lamat to lead us through the rest of the MSQ unless they actually remember to give the scions some personality back.
I mean, I want to be wrong- ideally I'd like them to make Erenville a Beastmaster (or just any kind of combat job) and have him as an ongoing companion/duty support NPC for content going forward since he has more character motivation to stick around than Wuk Lamat does. Maybe the animals are acting up because of some looming threat for the post patches? But that just sounds like prime Trials content, or possibly the exploration zone.
Side quests seem to say there are beasts acting up in other areas too (mainly in Yak Tel) and strange beasts start coming out of the cenotes, some of which are connected to the sea. If the animals are being agitated by some threat there then I could see those two things connecting later, but thats just my cooked up conspiracy theory lol
Hopefully they will just focus on investigating the mysteries left behind (which reflection did Alexandria came from? how did the lalafells get this thing to let them dimension hop?) and hopefully lead up to some interesting new areas for next expansion- either in Eorzea or another reflection.
That being said though, maybe having Wuk Lamat in small doses will be better than a whole uninterrupted expansion of babysitting her. And it will be broken up with other content too. As long as there's other storylines running alongside including other/new characters, I think it will be bearable at the least.
