G.I. Joe update: I finally just found a response to a fan question by the writer Paul Allor on Twitter five days ago. Someone asked, "This isn't the end of your run, is it? I'm a little behind and haven't seen anything solicited past #10."
Allor responded: "Nothing's been announced one way or the other, but this is the end of our first 'season.'"
Spoiler alert: None of the big baddies survived this very rushed issue. It was obviously meant to be an ending. Yeah, it's comics, and they could all come back somehow. But this is one reader who wouldn't return for that.
