The only really cool thing I've heard about it is the musical instruments thing. Some guy was saying that he was some guy playing chopsticks on a lute or something and he joined in on his drums. I could imagine really talented players actually creating bands or something.
Other than that, I hear it's just a WoW clone, like most other "better than WoW" new MMORPGs that end up disappointing.
The Fantasy MMO market is too saturated now imo with these clones. I'd like to see some truly revolutionary titles come out. A better version of UO would own ...I want to have my own castle =(.
