MMORPG in all it's senses.

@Marn: Yeah, cause everything in GW2 is absolutely new to the genre and nothing has ever been seen in another MMO before.^^
People need to use the search function and read up on the posts created by those who do their research. There is no grinding, exp or otherwise, and it is NOT a PvP based game. Please, people, use the search function and read (hard concept to grasp on a forum, I know) the stickied posts. There's a reason they have been stickied.
Guild Wars 2 doesn't bear a strong resemblance to many other games I've played or heard about, aside from Guild Wars 1 (which enjoyed rather limited popularity in comparison to World of Warcraft). I think the combat system and dynamic event system in particular are innovations which could be quite successful conceits in what has become a relatively stale field, auto-attacking all day, target locked spells, killing 10 rats etc. All MMO's are judged against WoW, which is why when Aion, Rift, and SWTOR came out they all were to some degree just WoW-clones, and they have not done well, because they have not managed to do what Blizzard does to anywhere near the same level of quality.
Guild Wars 2 though, according to Colin Johannson, is not competition for World of Warcraft; if anything GW2 would be a competitor against D3—although D3 is not truly an MMO, but rather just an action RPG/dungeoncrawler—as they both use the same pay-model of buy-to-play boxes with expansion packs. GW2 and WoW are both MMOs but as I said there are so many differences at so many levels of design that it is tough to really make a constructive and useful comparison of the two.
We've come to expect a very high quality product from the MMO field because Blizzard has been delivering an amazing product for years. They started out by saying they could do better than Everquest and Runescape and they pretty much did so, right from the beginning. Other games came along and they tried to release their own competing product to take on WoW, without taking the time to really offer a polished game that would attract lots of customers (and keep in mind they also did themselves no favor by having subscription fees, because lets face it, Blizzard is making a lot of money off subscriptions). I think Guild Wars 2 is not only going to be a fun game, but it is going to bring a breath of fresh air to the genre and prove you don't have to just rip off World of Warcraft and change the art and UI slightly in order to be successful.
GW2 is the next messiah and our lord and savior for the MMO world.
That's really all you need to know.
Similar to SWTOR in that it is very story driven, and you don't pick up quests in the traditional fashion. The main differences are with group play and character scaling.
There are very few truely new idea's left in the world to discover. What makes for new ideas is finding ways to improve and build on old ones.

I can't really describe what kind of game GW2 is. It's like an MMORPG but it has more of an action feel, no grind, and no gear treadmill.
It basically redefines the genre that is MMORPGs.
