Looks like their done as a couple. Or at least, done until someone of the not-Bendis persuasion gets their hands on them. Here's a quote from an interview Bendis did over at Marvel:
"Marvel.com: Speaking of love, Cyclops and Emma Frost went through some rough times during Avengers Vs. X-Men. How does the fallout affect their relationship?
Brian Michael Bendis: The romance is done. They are not together anymore romantically. It's pretty hard to come back from what they went through in Avengers Vs. X-Men. s were said, powers were stolen, and as we will discover in the very first issues of UNCANNY X-MEN, some things happen between them that cannot be taken back."
