According to a former writer here at VGRevolution.com, Microsoft is contacting people who have been a member of the service for 10 years and obtaining address information in order to mail them a “special gift.”
Shawn gave us more insight on the call he received seemed that Microsoft is picking random users who have been with the Xbox Live service since day 1.
If anyone else gets a call please let us know in the comments.
We’ve reached out to Major Nelson and Microsoft in order to verify this and to hopefully get an idea if this will be widespread. Details will follow as we receive them.
