While the style of game isn't new, there are few studios with the means to support an ongoing MMO. The most successful MMORPG, like "World of Warcraft" offer character storylines or regional quests to help players engage with their massive world. In its current state, "New World" will depend on its players to build a satisfying experience together, instead of providing a script. The game will essentially be a sand box for thousands of players.
Amazon has not said whether "New World" will be free-to-play, and there is no anticipated release date. The studio told visiting journalists that the game will be entering beta tests on PC "soon." Until then you can join the "New World" mailing list to get updates on the game.
