(in case y'all couldn't guess) Guild Wars 2. I've been looking forward to that game for... what is it, 3 years now. It's nothing official, but has been "hinted"...

(pay close attention to the RED text!)
Asuran robots (awesome!), Charr (Klingons): kitties with guns (more awesome!), Sylvari tree creatures (slightly less awesome, but still extremely exciting), Norn forms: Wolf, Bear, Raven, Snow Leopard! (as if being a giant wasn't awesome enough!) and Humans'... humanity... (yeah. maybe they have something else cool to offer)
I'm interested in several of the other MMO's on the list, but being broke I can't afford to play them.
PS: how awesome is a pet cat with laser vision? too bad my picture is just a charm skill. a man can dream though...
