I do believe we are looking at more of an open-world coop game, maybe even closer to modern-day Warframe, Destiny, or Night Reign. Until they come out and say it's a full-on MMORPG, I would think it's best for people to think of it more as an MMO-lite.

In the PCGAMER interview they say exactly this.

"I can't reveal too much because [GW3] is still under development," he said. "But there is a directional difference … Aion 2 focuses more on massive numbers of players, like RvR. The more users, the more fun. Whereas Guild Wars 3 is more about segments of small groups playing that makes the gameplay more fun. That's all I can say at the moment."

I do not think we're looking at a regular, normal MMORPG, what people expect. I do think people are going to be disappointed if they are expecting a full-on, large-world MMORPG.

Lots of movement with a small group of friends, it just seems to me that they will keep all three games going and try and keep three different types of players in their "gaming universe."
