How many of you have heard about Rift?

I haven't followed Rift for that long but from what I have read and see about it so far it has immense promise. Looking at how they deal with the class system (and the individual classes themselves) is fairly impressive.

I'm hoping to get invited to one of the Beta events that is happening soon so I can check it out more in-depth. Anyone else tried out the Beta or has anyone been following it?
