Yeah I hope we get the shiny Rayquaza too, that would be nice. Since it's movie related I think we have a better chance of this than some of the others.
It'll be interesting to learn more about Hoopa as the movie gets closer to release. That means we should see it about November or December of this year, as we did with Diancie and the Cocoon of Destruction and then have the card released about that same time. I already half predict a Hoopa collection at the end of the year like we did with Diance/M. Diancie, though I wonder how this unbound form will translate into the card game. Will Hoopa's release coincide with X2Y2/Z? Or will that be reserved for Volcanion?
I have to say though I rather wish that instead of having something to do with Hoopa it would instead have something to do with Zygarde. I mean we've already known about Zygarde since XY and yet we haven't heard anything about it, and we don't even have in in card form. At this rate we might have a Hoopa card (or two if the form comes into play) and we haven't gotten one of Zygarde. Even Diancie and its mega form came out before hand, this just seems kind of unfair to Zygarde that he keeps getting pushed back. Is this going to happen with Volcanion too or will Zygarde actually get priority over one Pokemon that was revealed after he was?
Okay, Zygarde rant over.
The other thing I want to know is what this will say about the Pokemon that the group will have caught by then. Will Ash finally get a grass type Pokemon, which is something that has annoyed me to no end? Will Serena finally catch something other than Pancham? Will someone finally have a fairy type other than Dedenne? Who will have evolved by then? I'm all but certain that before the series is over Fletchinder will evolve to Talonflame and Frogadier will have evolved to Greninja.
Really though, I think it would be an interesting kind of movie to have all the legendary Pokemon around, maybe bring back all of the major characters from the series. It could be a special point where those with the ability to have mega Pokemon like Ash and May to actually mega evolve them, that kind of thing.
