Nope, I'm an engineer... less BS and more analytical thinking than Politics.
Saying that the Dec. 15th is false because the 9th was false is like saying there will be an Earthquake on Friday because there was an Earthquake last Friday... there is a no correlation between the two events. Now if there was an earthquake every friday for the last 3 months, it would be a safe assumption that there would be one this friday, but only once have stores received any devices and started leaking out info about a release date which then fell a part. There is zero indication that a pattern has developed and therefore there is no reason to speculate that the Dec 15th date is false beyond permission and just being plain ole grumpy.
Which is more crazy, for someone to believe that it will come out on Thursday because it is what we are being told or to believe that it won't come out Thursday because it happened once before and one has a "feeling"?
