Kindle Fire is still 6 weeks away from launch but data leaked by a verified Amazon source to Cult of Android suggests that it’s set to be the biggest tablet seller on its premier day. The sales are chalking up at 2,000 units per hour and up to 50,000 per day, as shown by a screenshot allegedly from Amazon’s internet inventory management system in Alaska.

Since the Kindle Fire went live on the site, over 250,000 tablets have already been pre-ordered.  If this rate of consumer demand continues, it’s going to reach 2.5 million pre-orders before its availability on November 15. Amazon looks like it’s shaping up to have the biggest tablet launch in history, outperforming even iPads 1 and 2 in their first month.

The first iPad only sold 300,000 units on April 3, 2010, and it racked up to over a million in its first month.  iPad 2 followed in March this year, and it sold 2.5 million units in its first month. These figures may look low compared to Kindle Fire’s, but they don’t look meager at all compared to that of the other tablet players. Motorola only sold 100,000 Xooms in its first month-and-a-half, while RIM’s Playbook sold an estimated 250,000 units in a month. Compared to Kindle Fire’s preorders alone, the figures from Motorola and RIM are heartbreaking.

Kindle Fire is not only dramatically outdoing its tablet competitors, but other e-readers as well.  The B&N Nook Color only sold a million units in the first two months of sale.  And the Kindle Fire may just outpace earlier Amazon e-reader tablets, too.  It’s outpacing the 6-inch Kindle Touch, even after its price went down to less than $100, by 4 is to 1. Only 20,000 preorders have been made so far. The 6-inch Kindle Touch 3G for $149 has it worse, only locking in 12,000 preorders.

Despite all the speculation, estimates and known figures, Amazon has always been discreet about their Kindle sales.  If it’s going to be a little difficult for the iPad from here on, it’s going to be worse for other Android tablet manufacturers.  The iPad is sitting in the high-end market, while Amazon’s hogging the low-end.  For everyone in between, it’s an uphill battle.
