And the price will determine how smart the Shadow was and how deserved the victory is. I think that at the very, very least, Rand will need to remain one handed and side-wounded, and some major Lighsiders will need to die.

Bashere and Tenobia are unlikely to survive IMO as that will pave the way for Perrin & Faile to rule Saldea.

Cadsuane will probably die, and lots of other AS too. Moiraine won't.

Many Aiel will die, since we've got to move from a "remnant" to a "remnant of a remnant".

Noal is begging for a Blaze of Glory to make up for his past, so I think he'll go down fighting.

Rand might lose a lover, but I'm not sure which one. Min seems most likely of the three as she's already spent far more time with Rand than the others and unlike Elayne or Avihenda, does not have a clear role for the post-TG world.

I'd be really, really happy if Gawyn died. So far nobody else in his series (hell, no-one in any series I've read since I started WoT) has come off as poorly as him. Egwene can do better... just about anybody else in Randland would be better.

Loial will convince the Ogier to fight, but like the March of the Ents, there will be losses.

And for reasons I won't go into, I think the Sea Folk might get pretty much obliterated.
