River Song is practically a time lord now.

She had the regeneration ability (which he drained in order to save The Doctor in the "Let's Kill Hitler" episode) and she can drive the TARDIS.

An interesting implication of the River Song business: A human baby conceived in a TARDIS during travel becomes endowed with Time Lord characteristics. This creates a strong implication that the Time Lords themselves are descended from human time travelers. In the series, humans from the 54th Century have developed time travel technology (used by Captain Jack Harkness and River Song). Who's to say that a group of future time travelers refine their technology to create TARDIS machines, and then settle on a planet called Gallifrey in the distant past and call themselves Time Lords?

River drives the Tardis better than the doctor. When he asked why it doesn’t make the noise when it lands with her driving she said it was because he leaves the parking brake on.

The Doctor: "No, you look Time Lord. We came first."
