Do you guys know if the Essentials character sheet will be available under the CB, i.e. if you'll be able to choose it instead of the standard 4E sheet to print your character once you're done building/upgrading it?
Should be. All you should need to do is go to the Campaign tab and un-check everything but the Essentials books.

FWIW, I think it would be useful to have, in addition to the individual book and item-level checkboxes, checkboxes for 'essentials','players handbooks', 'power series', 'dragon magazine', 'Eberron', 'Forgotten Realms', 'Dark Sun', and 'other'. (the campaign settings would disable campaign-setting specific material for other settings, and for Dark Sun, would disable divine classes and turn on inherent bonuses).
I'd just love to have a "uncheck all" button.
