Following the successful launch of its first tablet last week, Amazon reportedly plans to launch a second model as soon as the second quarter next year. Fresh off an apparent miss — Asus went on record in denying an earlier report from the site on Friday — DigiTimes cites unnamed sources from within Amazon’s supply chain in claiming that the company’s next Kindle Fire tablet is scheduled to launch by the end of the second quarter 2012. The site reported earlier this month that Amazon’s 8.9-inch model would follow the 7-inch Kindle Fire, bumping the 10-inch quad-core “Hollywood” tablet BGR exclusively revealed into late 2012. DigiTimes also noted that Foxconn has been added as a second ODM for the current Kindle Fire, and it will join Quanta in mass-producing the 7-inch slate in the first quarter next year.
