Bleeding Cool is reporting that the new issue of Marvel Previews lists X-Men #9 and Eternals #10 under the banner "Judgement Day is Coming". Given the Eternals #10 solicit referencing a conflict with the Avengers and a Summer event, as well as the Gillen/Duggan Avengers/X-Men FCBD issue, it seems likely the this is a crossover between Eternals, X-Men, and Avengers, likely relating to the Celestials finally coming to judge Earth.
