Frankly I think he already has moved on from his Rose issues, but here's another thought: both Nine and Ten have the "last of the Time Lords" etiquette as deep part of their self definition, with even the Master's return not really changing that. I don't think New Who will do something as radical as bring the Time Lords back as a people, because that would mean giving up on one of the key changes they made, but what I could see them doing is restart the Gallifreyans, on a basis that means while there won't be any around to interact with now, there will be in a few centuries, making the Doctor from the last of something old to the precursor of something new.

...maybe. *frets anyway*
