Up Above are The Corocoro Magizine and Screenshots of the New World Tournament Feature in Black & White 2
You get to battle previous Gym Leaders and Elite Four members, whom you download through Wi-Fi (apparently the characters themselves and their teams). You can participate in either single or double battles against them.
Will you get to also battle previous other characters in the games? (Eusine, Barry, Ect) Will it effect the story?
