Falling in line with the positive news regarding Kindle Fire sales, iPad 2 also received a significant bump in sales on Black Friday. From AllThingsD:

Piper Jaffray analyst Gene Munster surveyed a few Apple stores on Black Friday and found that iPad sales per hour were 68 percent higher than they were a year ago. On average, the stores Munster visited sold about 14.8 iPads per hour, up from 8.8 iPads per hour last year, more than enough to support the analyst’s projection of 13.5 million iPads sold in the December quarter.

Deutsche Bank analyst Chris Whitmore’s analysis is similar to Gene Munster’s, leading him to believe that iPad 2 sales are tracking in line with his estimate of 14 million iPad sales for the December quarter.
