I'm super excited for the events to come.

Yuya, some of his friends, and a couple strangers who are all on the same side (except one, presumably a double agent) have been drafted by Reiji to become a team, the Lancers, with the purpose of countering attacks from other dimensions, and Reiji is going to bring everyone with him to other worlds, starting with New Domino City, the Synchro World.

I'm guessing this is where Jack Atlas comes into play, and it's known that Yugo (Yuya's Synchro counterpart) is from this world, but the question is this:
Is this an AU New Domino City and not the one from 5D's? Because there's been mention of Jack and Crow, but none of Yusei. The popular theory is that, in this AU world, Yugo fills Yusei's spot. The show is giving off a bit of a Kamen Rider Decade vibe.

Either way, I'm psyched. ARC-V is quite the anniversary celebration.
