Update in the October news on WotC's website.
Looks like the name is Class Compendium: Heroes of Sword and Spell, and compiles the updates for the original PhB builds of Cleric, Fighter, Rogue, Warlord and Wizard, along with feats and explanations of how they interact with Essentials mechanics. 6x9 paperback format, almost like a "Next step in complexity" from HoFL.
That news article is awesome, simply because it has a picture of a chicken typing at a computer.
