After Amazon.com Inc.'s official announcement this week introducing its 7-inch Kindle Fire tablet for just $199, rumors are rife the company may bring out its second-generation tablet with a 10.1-inch screen this year.

The bigger competitor for BlackBerry's PlayBook might hit the markets around Black Friday, according to Tom's Guide,

Even before Amazon officially revealed its 7-inch 'NOOK Color Killer' tablet, the Kindle Fire, we already heard reports that it would be just a teaser, that something bigger and better would follow close behind in early 2012, a report on the technology Web site said.

Amazon announced its Android-based handheld device on Wednesday, apparently forcing Research in Motion to cut the price of its BlackBerry PlayBook.

Amazon's 7-inch tablet will be released Nov. 15, and it can be pre-ordered now.
