As it stands, Loki season 2 marks one of the only live-action Marvel series returns, with only What If...? outside of it having a confirmed second season. Other than the fact that the God of Mischief will be back for more small-screen antics, though, there's not a whole lot of concrete info out there about what's to come.
That's not to say there isn't enough out there to tide us over in the meantime, however. Marvel may like to keep things under wraps, but the studio has confirmed who will be back for round two (both in front of and behind the camera), provided updates on when filming might start, and teased when the new episodes may potentially be released.
