While we expect Amazon to refresh its Kindle Fire tablet sooner rather than later, Demos Parneros, president of US retail for Staples, has told Reuters that the online book-seller has bigger plans. Amazon apparently aims to introduce five or six new devices (or SKUs, stock-keeping units), though as noted by Android Central's Phil Nickinson, these could thin out to just two tablet models and several storage variants. According to the exec, the tablets will come in a range of sizes and would include a new ten-inch device -- going directly against another popular tablet. No word on whether these five or six device would include a smartphone, as screen sizes get increasingly closer. Amazon has also announced that it'll be creating a new R&D hub in London, focusing on its services and APIs for TVs, consoles, smartphones and PCs, aimed squarely at rolling these out across the globe. The original Kindle Fire -- and its Android app store -- is still not available outside of America. However, public plans for the new Amazon base currently center on relocating both Lovefilm and Pushbutton to this new hub. However, it's been about a year; about time for Europe to get a taste of Amazon's wallet-friendly tab.
