Because of potential spoiler hints I don't think R/A, U/J, B/G, or R/K are eliminated.
That leaves M/G and L/A.
I read on some board that Gretchen was rumored to tell someone that they do really well for an "old" team. Also, from Ray's interviews over the last week, I don't get a sense they he spent any time in Sequesterville with Meredith and Gretchen. Therefore, I'm guessing they make it to India.
That leaves Lynn and Alex, who I think will be eliminated.
