can I expect anything different from the upcoming AV holiday, compared to normal AV games?

Hello,Just got to 60 and I'm grinding a few ranks in PvP. I did a whole bunch of AV from 51-60 for the crossbow and exalted reputation. I never participated in the AV holiday and there's one upcoming this thursday night. Is there anything I can expect to be different?Are queues going to be shorter by a large margin? - Right now I'm getting around 40-60 minutes queues.Am I going to see premades make it into games somehow? I know they changed something, but I'm quite sure I've seen a few Russian premades for example.Can I still expect to win a majority of my games, as a horde?
