You've probably noticed by now, the game is being patched with goodies! And it's a BIG ONE. There's been no particular news on it, except a statement in Abby's blog that says this:

"But don’t worry, you’re about to find out in a matter of hours, so stay tuned for news on the HKO Event blog. A patch update should be coming up for that and some other things too, so stay tuned!"
