I guess what I'm saying is that there weren't any problems inherent in Emma/Cyclops.
With that said I'm otherwise just as excited as you are! I thought I'd be upset, but it just isn't in me. I'd rather know that when I pick up ANXM and Uncanny X-men that I'd be able to get back to reading something I was comfortable with... but I'm just happy to get my Emma back. The future should be bright for her.
Mike Carey... Did Rogue fans not like him? I really have no idea. I read his Legacy for a while, back when it first launched, when I was on a "I'm going to read every X-book" kick and eventually I just realized I wasn't enjoying it. But he really pushed Rogue way to the top. I thought Rogue fans would like him.
