It's really quite possible that in TGS Rand and Egwene's story lines mirror one another as Perrin's and Rand's did in TSR. That would explain why Brandon decided to stack them together instead of Perrin + Rand, Egwene + Mat, for example. From another report, I understood that Brandon said TGS has the build up to TG from two story lines (Egwene + Rand, it seems), and 'teasers' for clusters 3-4, while book 13 will have the core events on the same timeline for Mat and Perrin, and the second part of the books will bring together everything. So basically, we could say we have the first 2/3 of Rand and Egwene in TGS with 1/3 or Mat and Perrin, and in book 13 there will be the last 2/3 of Mat/Perrin and the last third of Rand/Egwene. Linda and myself expect that cluster #5, in which Brandon put Elayne, Taim, the Bordermen etc. will be mostly absent from TGS.

The only worry I have is that it sounds fairly similar to what RJ attempted with WH/COT/KOD. It worked for me, and I don't mind that much to have to wait one more year before really getting into Mat/Perrin. I probably have to brace myself even more for the fact the book will be highly criticized. It's what I dislike about CoT - the fact more time is spent defending/attacking it than discussing it.
