I think they explained a number of things about what happens with the time-lords, the TARDIS and not only how they began but how they learn. This information was used by moffit to create a decent explanation for River's abilities.
We know that when the Time-lords are young they are taken to the Eye....they look into the vortex and can begin studies as time-lords. Their ability to percieve time and live a long time as well as the regenerations are by products of exposure to the void, vortex and must be some type of adaptation given also by the TARDIS.
The TARDIs are grown....which could mean they live as well. They showed a wonderful human interpretation of the TARDIS earlier this season which further suggests she is a living entity. It is a wonderful thing too. She communicates with those inside her and gives them abilities such as the language thing they explained.
Rory and Amy did the deed and created Melody in the time vortex aboard the TARDIS so it would be assumed that like the , timelords who were not born originally of the vortex but adapted to it by being concieved within it, is essentially a Human Time-lord created as the Galifrey Time-lords were. She has some of the same abilities but they will also be different because she is human with only one heart (or is she).
I also hope they do something with the doctor's daughter in the near future as she has not been exposed to the vortex but was made from his DNA....River and the doctor's daughter ....what a conbo.
I think they will do more , much more with this idea in the future.
Later,
