Marvel Studios announces the premiere window for WandaVision, its Disney+ series starring Scarlet Witch (Elizabeth Olsen) and Vision (Paul Bettany). Both characters were of course introduced to the MCU in 2015's Avengers: Age of Ultron, although Wanda spent some time on the side of evil before realizing she'd been misguided. Vision, meanwhile, was created by Tony Stark and Bruce Banner in order to try and stop the rampage of the titular malevolent A.I. He did so, and the world was saved, at least for the moment.
In Captain America: Civil War, Wanda and Vision were shown to be developing feelings for each other, which had blossomed into a full-on romance by Avengers: Infinity War. Unfortunately, Vision's continued existence depended on the power of the Mind Stone, and that was one of the items required to power Thanos' Infinity Gauntlet. The Mad Titan of course ended up successfully snapping away half the life in the universe, with Vision meeting his tragic end directly beforehand.
Earlier this year, it was revealed that Scarlet Witch and Vision would return to star in WandaVision, a streaming series for the upcoming Disney+ subscription service. It was unclear how that would be accomplished, with Vision quite emphatically killed off, but that didn't stop fans from getting excited to see the duo in action once again. Now, during Marvel Studios' Hall H panel at San Diego Comic-Con 2019, the company announced a spring 2021 premiere for WandaVision.
Later in the Marvel Studios panel, it was revealed that, rather than go the prequel route that some fans had expected, the WandaVision Disney+ series will indeed be set after Avengers: Endgame. Considering Vision was still very much dead after Endgame concluded, that leaves an obvious hurdle for the series to jump. Thankfully, Marvel already seems to have their path to doing that in place, with the announcement that Doctor Strange 2 will both deal with the multiverse and include Olsen as Scarlet Witch.
Logically, this is leading fans to believe that Vision will somehow be brought back to life using the multiverse, although it's unclear how exactly that will work. Wanda could conceivably transport an alternate version of Vision back to her present day, but that obviously wouldn't be the same Vision with the same experiences. Thus, using the multiverse to resurrect Vision could leave WandaVision's Scarlet Witch in a situation similar to Star-Lord after Endgame, pining for a Gamora that doesn't remember their love.
