Macmillan's Tor Fall 2009 catalogue reveals the TGS cover synopsis?

It seems we're looking forward to an Egwene and Rand centric boook, much as Linda and myself hoped. Very exciting news :)

This from MacMillan's website: (Thanks to Emma for the heads up)

A Memory of Light was partially finished by Robert Jordan before his untimely passing in 2007. Brandon Sanderson, New York Times bestselling author of the Mistborn books, was chosen by Jordan’s editor—his wife, Harriet McDougal—to complete the final book. The scope and size of the novel was such that it can not be contained in a single volume, and so Tor proudly presents A Memory of Light:
Gathering Clouds as the first in a short sequence of novels that will
complete the struggle against the Shadow, bringing to a close a journey begun almost twenty years ago and marking the conclusion of the Wheel of Time, the preeminent fantasy epic of our era.

In this epic novel, Robert Jordan’s international bestselling series begins its dramatic conclusion. Rand al’Thor, the Dragon Reborn, struggles to unite a fractured network of kingdoms and alliances in preparation for the Last Battle. As he attempts to halt the Seanchan encroachment northward—wishing he could form at least a temporary truce with the invaders—his allies work in desperation to forestall the shadow that seems to be growing within the heart of the Dragon Reborn himself.
Egwene al’Vere, the Amyrlin Seat of the rebel Aes Sedai, is a captive of the White Tower and subject to the whims of their tyrannical leader. As days tick toward the Seanchan attack she knows is imminent, Egwene works to hold together the disparate factions of Aes Sedai while providing leadership in the face of increasing uncertainty and despair. Her fight will prove the mettle of the Aes Sedai, and her conflict will decide the future of the White Tower—and therefore the world itself.

The blub apparently appeared first in the JordanCon program

It is not confirmed to be the cover blurb - it is from a catalogue Macmillan put together to promote their upcomin fall releases - though it sounds likely it's close or describe the focus of the book more or less accurately. Brandon has apparently hinted/told people at JordanCon that the book had 'teasers' from the other two main story lines, so a few thinsg are likely missing from this blurb.

PS: If you look at the catalogue, you'll notice that it still shows the working title 'A Memory of Light - Gathering Clouds', not The Gathering Storm they later decided would be the final title. See Brandon's Blog, his entry on the book split, for more details on how the title ideas evolved.
