Perhaps this is a clue that the online retailer is aware that new MacBook Pro models are to be released on Tuesday February 19th?  Speculation has been high surrounding potential MacBook Pro updates for the past several weeks.  The Amazon rebate (dates listed below) offers a compelling argument that current MacBook Pro models may be phased out in the near future as the retailer has often provided rebates on Mac models prior to the end of their lifecycle.

The MacBook Pro received its last major revision in June 2007 followed by an incremental processor upgrade option in November 2007.
