Amazon is reportedly preparing to launch a follow up to the company’s wildly successful Kindle Fire. The specs have not yet been finalized, however Amazon is expected to deliver samples to manufacturers by March, according to the China Times. The publication states that a 10-inch OEM device from Foxconn could be the final product. The report comes just after Pacific Crest analyst Chad Bartley claimed that Amazon plans to release an updated 7-inch tablet and a brand new 9-inch slate in mid-2012. BGR exclusively reported last May that Amazon was working on a 10-inch tablet, although a later report would suggest that Amazon was focusing on launching a new 8.9-inch device first. The next-generation Kindle Fire is expected to launch by the end of the second quarter.
