Not to mention they have only told us 7 or the 9 new areas. So they are leaving some stuff out...maybe Sharlayan and Ala'mhigo? Which could easily be translated into some big scale type thing for this expansion. We just don't know yet. Not to mention they have mentioned nothing on besides the fact there will be 8 new dungeons (not raids). And they also hinted that Bismark would be a unique battle (he is freakin' huge and flies...might be some hints there).

What I feel is going to make this expansion stand out from the 2.0 is the challenges which they are going to throw at us. I feel that they are really going to mix it up, mechanic-wise; which honestly is all this expansion needs to do.
