I have faith in Duggan not shying away from showing Iceman enjoying some men on men action. I'd hope he'd expand on the ever-so-present subtext of Kitty being queer, but that seems more like a Marvel responsibility than his and I'm not sure Marvel has any interest in investing on that.
The thing is this book has the 2 most high profile black characters from the X-Men (Storm and Bishop) and the most high profile gay character from the team as well (Bobby). Hopefully they'll have meaty roles like Kitty and Emma will obviously have.
