While all the other mobile manufacturers are concentrating on making small-sized/7-inch tablets more dominant in the market, it seems like Amazon is thinking of the opposite. An analyst believes that the online retailer will unveil a bigger 10-inch Kindle Fire model later this year, which would take on similar rivals including the iPad or the Google Nexus 10.

NPD DisplaySearch analyst Richard Shim told CNET that Amazon is “moving up to the 10-inch class” after having previously released two-generations of 7-inch Kindle Fire and the 8.9-inch Kindle Fire models. The new model will reportedly sport a 10.1-inch display with a 2560 x 1600 resolution (~300 pixel per inch (PPI), similar to Samsung-made Google Nexus 10 tablet.

Other specs aren’t revealed at the time and whereas the release date of the 10 incher Kindle goes, Shim believes that the display production for the tablet is ostensibly set to start in the third quarter, so it’s quite possible for the tablet to release early next year or at the end of 2013. Amazon is also expected to release an upgraded 7 and 8.9-inch Kindle Fire versions this year.

As far as today’s speculation goes, take it with a pinch of salt as analysts haven’t always made the correct call. Also, with the 8.9-inch version of Kindle currently present, the possibility of a slightly bigger tablet seems a little grim. Would you want a 10-inch Kindle device or do you think 8.9-inch is quite enough?
