Update: While earlier rumors pointed at a July 31st launch, a more recent allegation suggests that the next-gen 7-inch Kindle Fire will be shipping on August 7 instead. According to Pocket Now, this date comes straight from Amazon’s manufacturing partners in Southeast Asia and will supposedly only concern the seven-inch Kindle Fire tablet, pointing to a plausible earlier release for its 10.1-inch variant.
According to many news sources and rumors, Amazon will reveal the successor to Kindle as soon as the end of July.
This is believed by many to be Amazon's retaliatory response to Google's upcoming new Nexus tablet, which is expected to carry a similar US$199 price tag along with a 1.3GHz quad-core Tegra processor and a 7-inch 1280 x 800 resolution display.
However, details and specs surrounding the successor of Kindle are still hazy at the moment. Nevertheless, many expect the new tablet from Amazon to at the very least match the new Nexus tablet's specs.
Lastly, there's also talk that Amazon might offer a Special Offers version of the new tablet which we see it support ads that appear as sponsored screensavers. If this come to fruition, it could very well bring the price of the new tablet below US$199 and really give Google something to think about.
