All I really wanted as Jaimie Alexander back as Sif in Thor: Love and Thunder & Liv Tyler and Tim Roth back in She-Hulk; in order, Tim Roth, Jaimie Alexander, and then Liv Tyler. And I just got 2/3 confirmed this week, so I am elated.
And yes, I believe Taika Waititi mentioned that it was fortuitous that Jaimie Alexander had scheduling conflicts during Thor: Ragnarok, since she was slated to be killed along with the Warriors Three by Hela. Taika didn't write Ragnarok, but he is writing Love and Thunder. And thankfully for those conflicts, Sif survived Hela's attack, and now she gets to be back.
