Dawn of X is confirmed to have Wave 2 and Wave 3, all serving to "reboot" the X-Men as they say. We can probably expect a lot of X-books in the coming future. Whether it's revivals, new titles, concepts, solos, miniseries, whatever, share what ideas you'd like here!
Some ideas:
Academy X -- School-focused title based on the students in Krakoa. Less superhero, more slice of life and worldbuilding the nation.
Spider-X -- Team-up series with Spider-Man and the X-Men.
X-Factor -- Bring back X-Factor again, with members possibly including Multiple Man, Strong Guy, Siryn, Longshot and Penance.
X-Men '92 -- Curveball, but I'd love to see this again.
