It would appear that the appearance of L70ETC at the Darkmoon Faire heralded a couple of changes to the overall in-game events calendar. One fairly cool, and another that stands to cause some questions. It would appear the schedule for the Darkmoon Faire has changed so that once every three months, it will now cycle through Terokkar Forest, ostensibly in the location it is in now. For those collecting the new cards this is a useful change, as it saves you from having to portal back to Azeroth, and then hearth back to Shattrath just to get your item. For everyone else who isn't collecting cards, it gives you a chance to blow your fellow players to bits in a game of Tonks. It also marks the first permanent location with the Darkmoon Faire in neutral territory, which will probably lead to some fairly decent World PvP.
The other thing that is different with the in-game events calendar is that the Halloween holiday, Hallow's End is missing. Now, we don't know if this is simply an oversight on Blizzard's part since the Hallow's End page is still there (after all, they did just get finished with an awesome weekend full of Blizzcon festivities!) or if this is an intentional removal from the calendar. I do know that if it was an intentional removal, I'm going to miss getting those silly costume wands that you could use on other folks in your party. Sure, the wisp forms got annoying as they removed just about all chance of fighting. But it was fun to flap around as a bat, or try to make your Skeletal form jump -- and watch it fail miserably, thus just making it hop-levitate without moving its feet. And what about throwing rotten eggs at the opposite faction? There again, Blizzard may have something even spookier up their sleeves to start ramping up for Wrath of the Lich King... Perhaps another Scourge invasion? I guess we'll have to wait and see.
