Seems like what we got during Secret Empire was what they meant:
"The crossover issues will feature the return of the Hellions and the gun-armed mutant known as Random, but the characters fans would be more interested to hear about returning arrive in issues #8 and 9. That is where fans will see both Emma Frost and Polaris arrive to complicate the lives of the time-displaced mutant team for the foreseeable future. “It was always our goal to bring Emma back into ‘X-Men: Blue,'” the editor said, saying that while Frost has been through some dark times of late, she’s not turned into a villain."
Yeas that's it !!
Thank you I'm not crazy !
So do you think the "Hellions" team was New Tian X-Men we saw ? Or something coming soon ?
