No idea when they'll announce it.
XD;; I don't always read announcements. If I see it's about a promo event(like sims, harry potter, etc) I'm usually not very interested. But other things like EIs I sometimes stop and read depending on whether I have the item or looks like I'd want it. But yeah, I had to have read the announcements to know about this contest. I don't play zOMG as much as I used to anymore.
