i have gotten the impression that if there will be any additional content, it will not be moving on to TBC.. WotLK.. etc.
or there wont be a reason for me to play.
i dont need a virtual reset timer on my progression.
any dungeons/raids will be for level 60, but of course more difficult. requiring better and better gear.
i could see professions going over 300 though.
and maybe some new battlegrounds. brand new.
so any progression will not be 2.0 ... 3.0 ..etc
but rather, 1.13 1.14 ...etc
