The Russos are at it again with cryptic Marvel teases. Fans are thinking the Doomsday trailer could release at SXSW London this week.

I think it'd be weird to drop it now. They missed the corporate synergy of attaching it to Mando and Grogu a couple weeks ago. Comic-Con is in July. At this point, just wait until then.

Agreed, Comic Con needs some of that Hall H magic (and an immediate release after - not before). If Marvel are there, they need to make a big show of it (as well as announcing some new things).
