No, it's not too early to speculate!
Anyway, in my grumbling as I waited impatiently for today's blog post, I stumbled upon this quote from Eric Flannum in an interview, not sure if it's been discussed yet:
If you're familiar with the map of Tyria, you know what he's talking about with the "leaving the world open" thing. Basically we have no idea what is to the North, East or West of the map borders. To the South and Southeast, there is Cantha and Elona respectively. So which direction are they going to take us? We essentially know we'll be dealing with Zhaitan in the initial release, so what happens with the other 4 Elder Dragons?We have a rough plan for our first two expansions as well as a plan for what our live team will be implementing in mind right now. Part of our initial design was to purposefully leave areas of the world open for expansion.
It’s important to point out that these are very rough plans, because I think that fan feedback will be a huge factor in what we choose to include in future expansion and live team releases.
Elona is oppressed by Palawa Joko - no thanks to us - and has been likely turned into an entirely different landscape than what we saw in GW1. Kralkatorrik, the Elder Dragon whose name is the most obnoxious to remember how to spell (I got it right, I had to double-check though) and creator of the Dragonbrand, is also somewhere in that region.
Cantha is completely shut off thanks to the rising of Orr, and the isolationist empire that thinks if you ain't human you should GTFO. Not to mention the Jade Sea has probably returned to being an actual sea (lol see ya Luxons) and the Echovald Forest has become more forest-y. Perhaps "Bubbles" the deep-sea Elder Dragon is messing with Cantha? Or is he near the Ring of Fire? Who knows, he doesn't even have a real name.
Then there's Primordius, who the Asura certainly have a bone to pick with after driving them to the surface in the first place. What are he and his destroyers plotting beneath the surface of Tyria? I bet the Norn would like to knock out a few more of Jormag's teeth, sending us into the far, far, far Shiverpeaks. Or, will the new content not have anything to do with the Elder Dragons at all? What happened to the Divines? What has that @*^& Kormir been up to since stealing my Godhood? What became of Dhuum and Menzies? The Mursaat?
My personal feelings are the first two expansions will deal with Elona and the Far Shiverpeaks. We'll see the constant warring between the forces of Palawa Joko and Kralkatorrik and find some remnants of the Sunspears (or even the Forgotten?) to re-liberate Elona. In the North, with our new playable Kodan (I hope), we'll deal with Jormag and perhaps find some Stone Summit to slaughter and see what happened to the Dwarves. I don't see Cantha happening within the first two expansions, unless they group the Shiverpeaks and Elona together for the first one.
