There have been surprisingly few if any concrete leaks of Amazon's future Kindle Fire plans, even with the follow-up's appearance likely just hours away. Thankfully, we may have been given a last-minute peek into the company's strategy after an Engadget reader tipped us to some unusual activity in an app's hardware usage logs. At least a pair of hits have come from a new device identifying itself as "AmazonKFTT" instead of the much plainer "AmazonKindleFire" language attached to the original model. There's also signs that Amazon has upgraded the OS underneath to Android 4.0.3. We wouldn't anticipate this particular slate carrying a quad-core chip to tackle the Nexus 7 head-on, though -- unless the KFTT variant is just a firmware-updated Kindle Fire with a name change, the next generation should still have at least one dual-core tablet in the range. Here's hoping there are a few more surprises in store by the time Amazon takes the stage on Thursday.
