Ultra PRO has revealed their quarterly Pocket page Portfolio binders for Pokemon. These feature the artwork of SM11 Unified Minds.
Ultra Pro Pokémon Portfolio - 9 Pocket Unbroken Bonds ( Umbreon & Darkrai / Mew & Mewtwo)
Each 9 pocket portfolio holds 126 cards single loaded or 252 double loaded cards.
Ultra Pro Pokémon Portfolio - 4 Pocket Unbroken Bonds (Espeon & Deoxys / Garchomp & Giratina). Each 4 pocket portfolio holds 40 cards single loaded or 80 double loaded cards.
Note: This set will most likely exceed 252 cards. @MisterStolloss calculated there will be 257 cards in Unified Minds including the secret rares. So the 9 pocket binder will not fit the entire set if this is true.
