Looks fun, but nothing to write home about. When it comes to MMOs I rather stick to one until it's content runs dry or I feel I've had a good enough run to move onto the next one. There's still alot I wish to do and accomplish in XI still so I won't be leaving anytime soon.
I'm not gonna abandon what I have familiarized and enjoyed playing for 6 years for something that looks like WoW with a fresh coat of paint.
