I am pretty good at guessing things, such as what bands they have in mind.....
I saw a Blabbermouth thread which indicated that a band I predicted would be appearing will not be available.
Maybe this is a change that is pushing back an announcement?
I am sure they are not holding back an announcement just for the sake of doing so.
There are tons of shows before and after Powerfest weekend now, so I hope they can get something announced soon, for the fest's sake...
