Corrin. His weapon is one of the strongest personal weapons ever and in Heroes it's darting blow 2. I think they must have made a mistake as his artwork has the base form Yato but the sprite looks like the Omega version.
The art style and animation look cool. I think Tien doing something that did nothing is worse than Krillin doing nothing. Did Tien's level cap really early or something? He has literally done nothing but kikohos in the manga since Nappa and they've all been no sold. What a loser.
In the "Big Game Spot" trailer, Vision seems to be with Cap, Widow and I think Scarlet Witch is behind him and the stone is (looks like it is) missing from his head. This seems to be before the big Wakanda battle.
EDIT It KINDA looks like when Cap goes to greet T'Challa, the stone still isn't in his head. Maybe they'll fix him up with Wakanda Science.
