I'm putting my money on Peter Weller as Gary Seven and Alice Eve as Roberta Lincoln. Why? Because those two characters are the main protagonists in Greg Cox's two-part novel series "The Eugenics Wars: The Rise and Fall of Khan Noonien Singh." Roberto Orci is a well-known fan of Trek literature and I think may have even mentioned those novels as being among his favorites. If true, Seven and Lincoln might figure into an extended prologue explaining Khan's origins, or perhaps in flashbacks throughout the film, which would fit with Abrams' penchant for non-linear storytelling. It's also possible one or both of them somehow turn up in the 23rd century time frame, perhaps to help deal with Khan after he is rediscovered by the Enterprise.
I also don't rule out the possibility that all the Khan rumors are nothing but a red herring, especially given Bob Orci's recent Khan-related hints, which somehow strike me as clever gambit to keep leading us merrily down the wrong path as long as we're already so eager to follow it.
Khan or no Khan, though, I still think Weller and Eve are playing Seven and Lincoln. Pull up a picture of Weller alongside Robert Lansing (who originally played Gary Seven) and tell me they don't bear some striking similarities. I would say their personal mannerisms and acting performances are also quite similar.
) That way, there isn't any time travel.
