Well storm is part of the X-men franchise which fox still owns the rights to and they have been more interested in milking Wolverine for everything his worth rather than exploring the other characters in the X-men universe.
Maybe now that Logan has closed that chapter they'll move onto others like Gambit, Jean & Cyclopse.
They already recast storm in the apocolypse movie so im sure you'll see more of her in phoenix but as for a solo movie you'll have to wait
Marvel are looking at doing their first female stand alone movie in Ms Marvel and also Wasp will be featured in the new Ant-man
hey,
well, Disney owns the rights to all Marvel characters so we wont have to worry about fox butchering any more characters. and I don't think anyone is excited about a Mrs marvel movie. she's another character that they'll have to sell to people that are into the cinematic universe. Why cant they just give us what the people want. They keep trying to make these lesser known characters special and ignoring the ones we all know and love.
