It's not really a reboot. They're basically relaunching the entire Xmen line in the wake of House/Powers of X. The groundwork Hickman is currently laying will set the stage for the next wave of X Books.
Ah ok. I saw another X-Men #1 and figured they were just starting over. I might think about continuing with X-Men and maybe X-Force if I really like HoX and PoX.
