Best Buy Books Bonus Bourne

Normally I recap the week's new spy DVD releases on Tuesdays, but I wanted to make sure to give an advance heads-up to potential Bourne buyers before tomorrow. Best Buy will offer an exclusive edition of The Bourne Ultimatum in a limited edition "steelbook" case (which I find kind of annoying) with a bonus disc containing an additional 40 minutes of material. I don't know exactly how limited this is, but the Best Buys around me all sold out of the steelbook versions of the two Grindhouse movies (which also contained bonus discs) by midday.
