Well it looks like there's certainly some sort of movement towards her origins story finally being told. Like others here- I just hope that it takes past continuity into account as that's vital (the 616/HoM Susanna Dane story) for it to make sense even as a comic book a storyline. But we don't really know what will happen :S
I'm not expecting anything big regarding Lorna and Alex's appearance in AvX- I'm expecting a prominent background cameo- enough to show off Coipel's amazing depiction of them atleast! :D Not sure there will be much, if any, interaction given what Nick Lowe said.
