DFO looks interesting (very pretty).
I am not so big on games where your skills reflect your play; as opposed to selecting your skills when you "level up". The former is more realistic, but it steals fun fun away from getting a little reward here and there.
I'll have to keep my eye on this one.
Another very unusual one to watch is Guild Wars. They will have a brief open-beta period next week during E3. It is made by ex-Blizzard employees who did BATTLE.NET and they plan on having an MMORPG with no monthly fee. It's also not a free-form world; instead it's MMORPG in cities where you congregate, but you group goes on private-instance missions. So it's a really different one. Could be really cool, or could suck orc droppings, we'll see.
