The end of Perrin and Mat's POV sections clearly comes before the end of Rand and Egwene's, meaning we'll have quite a bit of missing time to account for in ToM before they even catch up with where Rand and Eg stand now. I wonder how much more time we can expect to go by in Rand and Eg's plotlines before the grand reunion and outbreak of TG. Rand still needs to bind the Nine Moons, know the Amyrlin's anger (in the company of a Seanchan woman, most likely the artist formerly known as Tuon), and reunite with Mat and Perrin; I can't see all these characters converging any sooner than a few weeks later in Rand/Eg time.

Speaking of prophecies, we know that Eg dreamed of herself falling and needing the help of a Seanchan woman to regain her balance. In light of what happens in TGS, I can't think of any scenarios off hand that suggest themselves for putting her in a position where Tuon's help would be needed or even desirable.
