Despite being labeled an “iPad killer” prior to hitting the market, Amazon’s $199 Kindle Fire never really gave the iPad anything to worry about. However, it’s going to come back and take a second shot at Apple’s hugely popular tablet, and this time its chances could be improved by a larger display. If a recent FCC filing is anything to go by, the Kindle Fire 2 will be significantly larger than its predecessor.

Until Tim Cook climbs onto the roof of Apple’s Cupertino headquarters and shouts, “we will never build an iPad mini” at the top of his voice, the rumors will continue to circulate. The latest comes from “various analysts” who claim the upcoming iPad mini will feature a 7.85-inch IGZO display from Sharp, and will start at just $249.

Its first generation Kindle Fire hasn’t even launched hit store shelves yet, but already Amazon has the Foxconn factory in China knocking up its successor, the Kindle Fire 2, with plans to ship the device during the first half of 2012.
