Play! made a statement last year at the rotation that there would be an "extended format" and more details would be coming.
They warned everyone not to get rid of the BW, EP, and NV cards.
Almost everyone I asked, in Indy, was undecided on how they felt about the format, mostly because no one knows what will get cut in August. However, the 2 biggest issues players have:
1. They don't have BW, EP, NV cards. They didn't get rid of them at the rotation, they started after. Will Nintendo do another print run of these sets so newer players can have access the them?
2. Two days, Two decks, too much testing. You can have the best day 2 deck ever but if you don't have the modified deck to get you there on day 1 you will never have the chance to use it.
I thought there would be separate, optional, sanctioned tournament on the second day during top cut.
