At first I didn't know what you were referring to, but there's now info on the Avid site. It apparently comes bundled with PT9 instead of 8, and it also comes with the Expansion Pack pre-installed:

Keeping in mind what it comes with, that would explain the higher price. But what's on the Avid site may be MSRP, and dealers may have it cheaper once it's out.
EDIT: Comparing the Mbox + Protools 9 bundles on the Avid Store site vs. dealers, applying the same type of discount to the Eleven Rack bundle, you could probably expect it to be about 10% cheaper than what's listed.
