They were implying she was alive, and that Kaine had rescued her from Norman's minions, but then the storyline did a hard swerve into Aunt May being alive and a prisoner of Norman instead. The only time she's been mentioned since is Millar's run, where Scorpion believes Norman killed Peter's baby.
It's unlikely any Marvel editorial regime is going to allow her to be mentioned again, which will probably never change unless some star talent pitches a story about bringing her back and Marvel wanting to let that star guy do whatever he wants takes priority over their internal rules about how Spider-Man comics must be.
