In a predictable turn of events, CoroCoro has announced that depending on a player’s game, they’ll be able to download the opposite legendary. That means if you bring in White to the theater, you’ll get Reshiram, and if you bring in Black, you’ll get Zekrom. Bring in BOTH and you’re the real winner :p
I’m still waiting for Dengeki to reveal the new pokemon game. Exciting stuff.
