I honestly think its going to be dragons exalted on for sure. I have a feeling it might not be a rotation right after worlds, to keep many cards in for when EX battle boost comes out. Pokemon catcher is reprinted in japan already, probably also in battle boost. Then darkrai and mewtwo EX are getting reprinted, so by keeping dragons exalted the whole tin set of EX pokemon fall 2012 will be preserved. It would be weird if rayquaza was the only one that wasnt out of those 3. Also tornadus EX gets reprinted, rare candy gets reprinted.
