Amazon is reportedly preparing to launch an updated 7-inch Kindle Fire alongside a brand new 9-inch tablet this summer. Pacific Crest analyst Chad Bartley on Thursday raised his full-year Kindle Fire shipment forecast to 14.9 million units, up from his earlier estimate of 12.7 million. “We believe there is an upward bias, particularly from the new 7- and 9-inch models, which we expect to launch in mid-2012,” Bartley wrote in a note to clients. BGR exclusively reported last May that Amazon was working on two tablet models, the 7-inch “Coyote” that ended up launching at the Kindle Fire last November, and the quad-core 10-inch “Hollywood.” A later report would suggest that Amazon tweaked its tablet roadmap, however, pushing the release of its 10-inch model back in order to first launch a new 8.9-inch tablet. Bartley also lowered his shipment estimates on Amazon’s E Ink Kindle eReaders from 28.6 million units to 24 million units.
