GATE 7 special chapter to be published in "Jump Live"
GATE 7's appearance in the magazine is listed to take place in the future, you can see it listed in the magazine's upcoming line-up here and here.
This could mean that the relationship between CLAMP and Shueisha hasn't been compromised and the reason why GATE 7 is currently on hiatus may lay on different, yet unknown issues.
More information as they come!
Thanks revolution_d1 for letting me know about this! ;)
