I think that there is a good possibility of Microsoft doing something with the RT on Black Friday... a few years ago, 2007, they sold the Zune 30 on Black Friday for a door buster price of $100 (that was the same year that they released the next gen Zune 80). That caused the Zune 30 to be one of the most sought-after gadgets that holiday season and drew attention to the Zune 80. Microsoft severely underestimated the demand of the 80 that year.
Lol, i got the $100 zune at that time. At any rate, I don't think this will be the same. MS has too much at stake to start a firesale this time around.
