Amazon's (AMZN +0.2%) 2013 Kindle Fire lineup will feature tablets with higher display resolutions than 2012 counterparts, "trusted sources" tell BGR. The regular 7" Fire ($159, 1024x600 resolution) will be replaced by a model with a 1280x800 resolution, the 7" Fire HD (recently cut to $169, 1280x800) by one with a 1920x1200 resolution, and the 8.9" Fire HD ($269, 1920x1200) by one with a 2560x1600 resolution. The new Fires will also reportedly be lighter, sport "a more angular design," and have an improved button layout. The hardware is expected this fall, possibly in September. IDC estimates Kindle Fire shipments (not the same as end-user sales) totaled 6M in Q4, and 1.8M in Q1.
