The most recent rumour now says there's an Excalibur series in development. Likely in the MCU and live-action, following also several rumours of Captain Britain's introduction in this universe.
Just a rumour, but I do not doubt these kind of ideas are being considered since the X-Men are joining in probably less than 5 years.
However I just really, really, really wanted this to be true
and an animated series set in 97's universe. So other characters could get some spotlight here too like Kurt, Kitty, Rachel and Colossus.
One of my biggest hopes for Marvel moving foward is more stuff, like animation, developed with
NO connection to the MCU.
