Oh boy! A new rumor that has me absolutely fuming if it is true.
According to this post on XBox.com, there is an internal Best Buy document that says that new Xbox360 Premium systems will include a 100GB HDD instead of the previous 20GB HDD. This is a huge step up if true, the only reason we can see MS doing this is if that Direct TV downloadable TV show rumor was also true. Rumor mill for now.
Can you imagine? I bought an Xbox 360 Premium, I supported Microsoft in their launch, and they go and give the late commers a 100GB hard drive. They better allow me to switch mine in, and copy my data over to the new drive for an insanely cheap or free price point, or I will be big time upset.
