I enjoyed their dynamics in Creed's X-factor hound career, so I expect their encounter in the future.
But in other ways, I think bringing back Wild Child is another evidence that X-Office has utterly given up taking advantages of Sabretooth's inverted ego. Imagine they find out Wild Child is much more well-received than good-guy Sabretooth lol.
Wave II books has been gradually announced. Guess Creed's gonna play as a Krakoa prisoner, rebel, exile or somehow traitor in one, if there are writers wanting him. Maybe Hickman's gonna mention his exiling state in his X-Men. That's what I think could be Creed's most possible plan.
