Exactly. No one said all of GW2 had to be about Elder Dragons beginning to end. Tyria holds so much potential for any fantasy story possible, so whatever comes next, I doubt it will be GW3. I sure hope there won't be a GW3 for another decade at least, because it would suck to finally get a good storyline and pace and all the new updates (build templates, legendary upgrades, UI update etc) added only at the final stage of the game - that's like upgrading a car with all the goodies you've always wanted it to have only to sell it shortly after.
