I am told the same thing is happening in Thanalan. 9:30am EDT today, an NPC named Alfgar outside the Ul'dah Adventurers Guild started saying that the Empire is attacking Ul'dah north of Camp Horizon. I didn't investigate because I had business in Limsa Lominsa. But when I asked another player in Limsa (yes Virginia, players do now talk to each other), she said that she participated yesterday and that she had alot of fun.

This is all hearsay though. So I suggest those interested investigate these events for themselves, and see what it's like.
