Well it looks like we won't have to wait 6 months for the first episode.
I thought this season would introduce other duelists who could chaos exceed summon. Not sure about story but the first episode's duel looks good.
More information found, Yumagained specifically numbers24, 66, 70 after defeating Faker.
It also looks like the Barians can create numbers from their memories willingly as they have shown Number 107 in the opening.
