I don't know if any official confirmation has been posted/linked on the 'Gym before, but here it is: http://www.pokemon.co.jp/special/wcs0809/card/ This Japanese special website about Worlds 2009 describes the structure and format for the upcoming prefectural, regional and national championships leading up to Worlds 2009. Scroll about 2/3 down the page, and there's an overview of legal expansions, clearly stating that the format will be DP On. This is something unique in Pokémon history - the main format will be the same for Japan, the USA and Europe + the rest of the world. I'm very excited. The pros clearly outweigh the cons in my opinion. Sure, the metagame outside Japan will most of the time be a slow, lagging copy of Japan's. But Japan's R&D team and card developers will for the first time ever design new cards based on the metagame WE ALL play in. No horror scenarios like 9-month GG dominations anymore. The next season is going to be incredible.
