So the other day when I went to Gamestop to preorder ORAS the employee asked me if I had gotten the Diancie code, I told him yeah and we got to talking about vidyas.
Well when we were talking he brought up how there is going to be another serial code distribution soon after ORAS comes out, but he couldn't remember what it was for.
With Hoopa's new form in ORAS, it's safe to assume that we will officially get Hoopa before the next game. Getting Hoopa this early seems unlikely though since it hasn't been revealed yet. But with the addition of the prison bottle in the pokebank update, I'm starting to think that Hoopa will be revealed soon after ORAS release alongside a distribution of prison bottles at Gamestop before Hoopa itself is actually released.

I'm probably completely wrong and we'll end up getting a shiny Pikachu, but the possibility of Hoopa soon gets me hyped.
