Why not both?
One of my favorite things in this entire game (that I wish I could replay without having to New Game+ it) is from 5.3, I think, when you're going through Amaurot with Y'shtola hostage and basically go through all the past events from the game. The part where you fight Estin-hogg and the music crescendo when you beat him and he shoots off into the sky still gives me some chills. Doing something like that for the entire game's story would be an amazing 10th Anniversary tribute, though I'm not sure how they'd do it that wouldn't feel like wasted Dev resources.
But to this day, I LOVED that sequence and still do.
That said, I didn't play before I joined in 2.3, but I've delved into 1.0 lore (Speakers Network on YouTube have a couple great series like Remnants of a Realm and The Rise and Fall series) and whenever I hear Answers reprise it gives me chills. I would love an event like that, or something like any of those things. For all the effort to distance 2.0+ from 1.X, I feel they're still one in the same in some respects. It's like a person who had a difficult past trying to distance from their own childhood or emotions and stuff when the best answer is to accept that part of yourself as well so that you can be a whole person.
I don't know what they'll give us, but I'll probably like whatever it is. Just saying you don't have to be a 1.0 vet to care about what happened before 2.0...
