I too want to see Emma and Jean meet again. It would be fascinating as they've never truly interacted extensively without the Phoenix looming directly overhead (early Morrison MAYBE, but you could argue against that as well). But right now we have no idea what Emma's status will be in the new run which will be the deciding factor in how Emma and Jean may approach each other, if they ever do. We're supposed to have a better idea after her issue of X-Men Black comes out.
The issue of Jean Grey's solo were they talked exemplified this. They were as civil as they ever were together, so not-friends but can tolerate each other without making a big to-do about it.
Also, this reminds me, according to X-Men Blue, adult Jean does have some semblance of teen Jean's memories. So does that mean she remembers all the time she spent with Emma when she was her pupil?
