No, the new thing is the Timeless Isle stuff. Only drops 496 gear, but you can use an item to upgrade things into the 530ish range.
Timeless Isle is pretty interesting, all things considered. I want to call it a sandbox zone but that's not quite right. There's tours and things, world bosses, a tough as nails pet tournament, and random Silver named mobs to kill and Silver named NPCs that sell rare things before quickly despawning. But there's not many quests that say "go here and do this" from a hub, you have to find a lot of it yourself.
It's more like a Guild Wars 2 zone than a sandbox, from what I've read about it. Haven't actually gone to the PTR to try it myself though.
