I'm excited for it too, but I don't see that havok, rachel, and lorna have as many connections as the rest of the group. And starting off with a space story leaves me a little cold.
I totally think there is connection. A book called Legacy and you have the daughter of Cyclops and Jean Grey. THe daughter retcon or not of Magneto and the brother of Cyclops. I think Havok and Polaris were really meant to be the next mutant royalty anyway. I love the idea of them joining the team. I also don't love the space story but maybe it will be only a couple issues and then we can get into some great stories.
