The first Kindle Fire isn't even out yet, but activity seems to already be under way to prepare for the manufacture of the next one. DigiTimes reports that LG Display and Chungwa Picture Tubes have begun preparing production capacities for 8.9-inch displays, which are expected to make their way into Amazon's second Kindle Fire tablet. It identifies LGD and CPT as the suppliers of the 7-inch screen inside the upcoming Kindle Fire 1.0, making them pretty good candidates to provide the hardware in any successors as well. The insider sources haven't ruled out a 9.7- or a 10.1-inch tablet either, although any devices in that size range would have to come later in 2012, following the introduction of the reputed 8.9-inch model.
