I actually saw a ton of people running around Gridania and the Black Shroud today, and there were actually people at Camp Drybone, too, when I went there, and people grinding at the new beast camps as well.

YESSSSSSSSSSSSS.

EDIT: And Ul'dah had a shitload of people in it, too. I have yet to check the wards for each city though :P I mostly just grinded today.
