I don't know if anyone else has noticed but there seems to be a lot of foreshadowing in EotW and the other early books. In EotW's prologue Mat, Rand and, Perrin are working (a.k.a. sitting around) with some friends in the Two Rivers and there's a lot of foreshadowing in it.

Rand says "I'd like to be a king." (pg. XXV) and later becomes king of Illian.

Mat says " I'll recue an Aes Sedai and she'll reward me." (pg.XXV) and he's going to rescue Moiraine in aMoL.

 

Then, later in EotW, Rand has a dream about Ba'alzamon where Ishy comes up behind Rand while he's looking in a mirror and Rand watches their faces merge until his face beomes Ba'alzamon's. Is it just me or does this seem to foreshadow the Rand/Moridin(Ishy reborn) body-swapping theory being correct?

yeah there's a lot of that. Like Rand saying that he'd give his hand not to use the Power, or the nightmare at Shadar Logoth where Mordeth wants his hand. :P
