Ausiello had a new "Ask Ausiello" column today, and while Grey's was mentioned a lot, there wasn't really a lot of good scoop, except for this:

Tell me you can give me something on Grey’s Anatomy to hold me over until tomorrow. Please be my fresh air; don't you see I am drowning?
At least one of these things will happen before the end of the season:
• After breaking things off with Cristina, Burke will transfer to another hospital.
• Callie will reveal she's pregnant.
• Izzie and George will hook up.
• Izzie will be reunited with her daughter, and it's someone we've already seen on the show.
• Addison will be diagnosed with a life-threatening illness.
• Derek and Meredith's relationship will hit a roadblock when one of her exes shows up on her doorstep with one thing on his mind.
