I was watching "Silence in the Library" & "Forest of the Dead" and realized something. If River Song meets the Doctor in the future and recognizes him then does that mean that she's going to meet David Tennant or another version? If D.T. doesn't come back to the series then some how some way the writers have to create a version that will meet her in the the Doctor's Future & do all the things that she mentioned.
I think it would be great if they introduce a younger version of her in a Mini-Series or have her as a companion to the Newer Doctor.
What do You Think???
