We'll see. If they truly want to they will make her a vampire again.
Ask Hannibal King, once a vampire always a vampire. He was supposed to have been cured when Dr Strange cast the Montesi Formula, but he was reverted for the Midnight Sons junk of the 90's.
Though making her a vampire was pretty stupid.
I was never a Jubilee fan. For a while, her thing was being Wolverine's tagalong, and I really hate the concept of sidekicks. Frankly, there really isn't much place for most of original Generation X. The vampirism actually had the potential to be interesting for Jubes, but it never did, because Marvel really doesn't give a darn about vampires (or most of their supernatural).
She may as well get her powers and life back, so she can drift back into limbo.
