Everyone suspects that Amazon will announce a complete refresh of the Kindle Fire Tablet line and probably a new version of eink Paperwhite sometime in the new couple weeks. This fits with Amazon’s history of the Fire line (although the eink line tends to have 18 month refresh cycles.)
The guys over at GoodEReader.com have leaked specs and benchmarks. If these are true then it will be a solid refresh of the line, but no big changes or surprises. If you are into specifics of the specs and benchmarks head on over.
