Like the first English Black & White set, Emerging Powers's two theme decks, Power Play and Toxic Tricks, will be released early on August 17th. The theme decks feature a Krookodile and Scolipede that have not been released in Japan yet (they are not just alternate art), meaning they are probably from Red Collection. On August 31st, two weeks after the theme decks are released, the main set's booster packs will hit store shelves.
They can't be from Red Collection. Red Collection, as WPM reported himself, was going to feature the rest of the Pokémon (minus Keldeo, Meloetta, and Genesect) that weren't in Black and White Collection. There have been confirmed to be 59 unique Pokémon in the Red Collection (the same number of Unova Pokémon that have yet to be officially released as cards of a mainstream set) out of the 66 numbered cards in total. If the Krookodile and Scolipede lines were to be added, then that would result in 65 cards, leaving room for 1 Trainer, and more than 1 has already been announced.
I know that I've stated this in the other threads for it, but I might as well state it here as well; Emerging Powers will most likely contain English-exclusive cards. The Krookodile and Scolipede lines (Or even just a Krookodile and Scolipede, as the Boy and Girl Starter Decks have incomplete lines of those 2) are examples of these.
