Patience... they may announce it sooner but it depends on a lot of factors...

First, I'm sure that they have to double-check all of the post numbers (including double-checking that there were no other mistakes on the part of the Easter Bunny), secondly, we don't know exactly how many forumers participated in the egg hunt so there could be quite a few PMs for E. Bunny to browse through and finally, we must keep in mind that both moderators and all three of the admins have lives outside of the forums...
