Halo 3 Launch a Hoax?

It would seem that in the past day a lot of notice is being pointed to the Best Buy either goof or huge relevance of a secret. Best Buy has began accepting Pre-Orders for the upcoming FPS Halo 3. Not only that but the most bizarre is the date at which it states shipping. 11/16/05 is the date of the Halo 3 shipping based off Best Buy's website. The most curious about this information is the fact that Microsoft has already stated previously the title will be released the same time as the Playstation 3. So whether or not this is just a mishap on Best Buy's part it is still worth recognizing.
