Two sources say there is a hope through the talks that Gunn could return in some fashion, even if it's to develop and direct another Marvel movie. "An end-all verdict hasn't been issued and conversations with Marvel are still ongoing," says one source familiar with the proceedings.
This is text book studio spin. Disney are clearly aware of the controversy and are trying to satiate those criticising them by saying "Who knows what the future will bring?".
We know what the future will bring, Gunn will never work for Disney again.
He's been working in Hollywood, successfully, for decades (he made a fortune as a script doctor and wrote big studio films like the first Scooby Doo film for WB) and he'll continue getting big gigs off the back of GOTG so he'll be fine.
Disney are just hoping that this whole thing fades away now.
