PUSH BACK Xpack release date!!!!!

They should push back the new Expansion set. A lot of people that i have overheard or talked to have said they will b quitting becasue they have school and do not feel the need to level to 70 becasue its stupid. I personaly think they should move it back a year in between is a short time and more people need to get to 70 and get geared. They should move it back to at least in the summer. PLEASE REPLY!
