Here's some random facts:
There are 19 playable races.
15 Classes (3 tanks, 3 healers, 4 casters, and 5 melee) This is subject to change I'm sure... I think there were 17 classes listed but 2 got dropped. My info may not be entirely correct on this...
You will have 3 spheres - adventuring, crafting, and diplomacy. You change between spheres in town. Each sphere has its own level/advancement (of course) and potentially a separate set of gear. This should provide a more dynamic variety of things to do.
You can buy land and build houses.
Your houses, mounts, boats etc have their own hp and can be attacked/destroyed. You can take other people into your house / boat with you if you want.
Combat involves skills such as "perception" where you predict what the mob is going to do before it does it, and allows you to choose different ways to react (block, counterspell, counterattack).
Many abilities you learn will be learned from fighting the mobs who use them.
Seems kind of cool to me
