Been a while, but I s'pose that's what happens when Rona destroys the status quo of civilization forever! (I've beat Persona 5: Royal, Borderlands 3 (twice over), Super Mario World (four times over), Tomba!, and done about as much as there is to do in Animal Crossing: New Horizons (got bored with it; never managed to recruit Raymond.)
Ahem. Enough complaining.
MSQ looks as hype and epic as one could hope for the ending of the first major story arc. Elidibert somehow summoning Light-infused people (or copies thereof) to attack, raising phantom Amaurot from the seafloor, trying to kill Exarch G'raha, and what looks like a final showdown at the summit of the Crystal Tower. Get hype!
Sorrow of Werlyt is now Eozean Gundam vs. Garlean Evangelion. Closeups strongly suggest van Hydrus' combat data being loaded into Sapphire Weapon, as expected. (As awesome as this is, I question the sanity of the Imperials at this point - we've already defeated the Imperial commanders they're using the combat data of, so why do they think this is gonna help?)
Still little context for the YoRHa raid, but we do see Tomra being carpet bombed by Flight Units.
So, the big question: Will Exarch G'raha survive?
My money is on: probably. Following proper story structure, there will be an inciting incident from Elidibert, rising action as we fight off his forces, a climactic battle at the summit of the Crystal Tower, and denouement as the Scions say their goodbyes and return to the Source. If Exarch G'raha is killed they won't have the opportunity for that denouement, so whatever happens I'm betting on him surviving at least until the end of the MSQ arc. (The lines about us forgetting people we've helped feel oddly meta to me...)
Interview with Yoshi-P on GameSpot says to brush up on Heavensward for 6.0, so no Garlemald yet - it's lookin' more like Meracydia or Sharlayan.
Aaaand yeah, no Deep Dungeon this expansion - instead there's the Southern [Something] Front for the Save the Queen quest, which scales with level and stuff.
Stay frosty!
