It's going to be nasty, but I have a feeling that Rand will earn "the anger of the Amyrlin" by telling Egwene that he needs her to deal with the Seanchan after she went through all this trouble to prepare the Tower to help him at Tarmon Gaidon. Mat seems likely to either join her in this endeavor or act as an ambassador of sorts to the Seanchan - these two are tied together; they have been since Egwene Stilled Amico a few minutes before Mat walked in and was able to release them without being destroyed by the Black Ajah Sister.

I think Rand is not going to be in the thick of a lot of the action, and his battles will be more personal (possibly supported by two Aes Sedai and/or Min) while Logain, Elayne, Nynaeve and Lan take on the Shadow.

That said, with Rand out of the picture, it will probably be 75/25 in favor of the Shadow with the Light winning by a deus ex machina move. Sorry, but there are way too many subcharacters not to have a whole rack of them get killed during Tarmon Gaidon.
