During Nintendo's Treehouse Live stream today at E3, they revealed a new 4 player battle mode called Battle Royale. In it, each player can have up to three Pokemon but only sends out one at a time. The battle is over when one of the players is out of usable Pokemon. To determine the winner, players are ranked based on how many Pokemon they were able to knockout, and how many Pokemon they have remaining.
During the same Treehouse event, Nintendo also revealed four new Pokemon.
Soul Heart, the only new ability among the list, seems to increase Magearna's Special Attack when a Pokemon faints (it's not clear whether or not this is restricted to only allies or if the Pokemon increases its Special Attack when opponents faint as well).
