Bleeding Cool first brought you the news that Marvel had cancelled Guardians of the Galaxy #151, solicited for January 2018, while #150 was still planned to be published.
Replacing it in February is Infinity Countdown: Adam Warlock and Infinity Countdown Prime, following on from Guardians of the Galaxy #150, with the second part of the return of Adam Warlock in which he goes on a quest with Kang The Conqueror for the Soul Stone. You know the one that the recent Infinity War suggests may be in Wakanda.
No Guardians of the Galaxy comic was solicited for February. We have now learned that it has definitely been cancelled as an ongoing series. Until the inevitable 2018 relaunch of course, which we have also been talking about for some time…
Also ending in January is Jean Grey with #11, which will, after the Phoenix Resurrection series also shipping in January, launch the X-Men: Red series in February.
