I read the Avengers issue and it is really hard to say what it was hinting at with cave woman Phoenix or the vision of a new phoenix. I'm still skeptical about Jean becoming Phoenix again anytime soon even though I would think Hickman would want to use it (but maybe in the future since he plans for the long haul).
Back to current X-books... I look forward to Jean being back in X-force next issue and I look forward to her showing up in Hickman's X-men book. We already know she's on the cover of a couple issues coming up (not the very next one but the ones but I think the two after that).
