It's looked for a while now like Vision would be one of the big casualties of Infinity War and Avengers 4, thanks to the Infinity Stone in the middle of his forehead that's probably a difficult thing to shake off given Thanos' desire for it. In the end, he was killed off by Thanos (having already been killed off by Scarlet Witch just before that and revived) as the Stone was plucked from his head. There have been strong rumours that he'll be back for Avengers 4, thanks to the time travelling storyline, but it's hard to see a way forward for him when the Stones will presumably have to be dealt with in some way at the end of that sequel.
Perhaps we'll see a redo of the sequence where Shuri tries to unpick the Stone from his consciousness to allow him to live without it, only this time successfully? That might make some sense. And it would explain how he's going to survive Avengers 4, because that's what the latest news is suggesting.
According to SlashFilm, Vision is set to appear in Scarlet Witch's already-announced Disney streaming platform TV show alongside Wanda in what would appear to be a shared top billing:
"The other thing I’m hearing is that Paul Bettany‘s Vision will have a large part in the previously reported Scarlet Witch show. In fact, it may actually be a series more about the super-powered couple than just Wanda. This makes sense to me, as Wanda’s relationship with Vision is more compelling than Wanda on her own, and the two have a long and fascinating relationship in the pages of Marvel comics."
It's about time we got to see more of Scarlet Witch and her relationship with Vision in the comics has always been a compelling part of it. It'd just be a little bit of a shame if it ended up just being a suburban romantic comedy like it devolved into for the first half of Civil War. Wanda is far more interesting when she's not domesticated and she's exploring the volatility of her powers and her own identity. Let's just hope that's the direction they're going to take.
It certainly can't be a prequel, because there's so little for the pair to have done between the end of Age Of Ultron and the start of Civil War to warrant a series. She was training to be a New Avenger and he was learning Sokovian delicacies to impress her while wearing roll-neck jumpers for some reason. That is not the strongest foundation for a TV show. So it would seem that this series will be a direct follow on from Avengers 4, once more confirming that the pair should survive.
