Makes sense to me....
Actually it does make a whole lot of sense.
It kind of goes with the fact that a lot of pre order folks had the status change from prepared for shipment back to not yet shipped and other things that a clog in the logistics channels due to weather might have triggered. There has also been the inconsistent arrivals for pre-order folks as with the stores. Heck, it seems even two in the same city must have received them a day apart based on when they had demo models out and available.
I bet they wanted to have demo models and pre orders hit at the same time on the "two weeks" mark with the store availability shortly there after. That pretty much happened with everything just pushed a few days later. The stores might have even had an official sale date of Friday when a normal shipping schedule was assumed which could explain some of the inconsistent accounts of most people getting "no's" and some people getting lucky. Any on sale date was probably abandoned or pushed back but probably not easily communicated all the while since there might have been a chance they got stock.
The wait goes on. Sorry, I can't help this, but I'm guessing it will be a super Tuesday.
