The average age of those (foolish enough) to stand in line for hours on end was well under 40 crowd with alot of disposable income (ie they have a decent paying job and living expenses under control, or parental permission to $pend). That will account for several thousand customers picking up sales.. after that, it really depends upon the masses of customers who are "supposed" to flood in after the doorbuster deals are gone. Dobutful thats going to happen because most of the stuff that was at great prices already has a saturated market for the products. Most lcd tvs, digital cameras, gps devices, and computer peripherals generally last for 3-5 years and don't need to be replaced.
I personally can attest to very little activity in my town's surrounding blocks late Thursday, and early morning hours Friday. My expectation is that they either shopped online, or not at all (yet).
