Marketing visuals for the upcoming Kindle e-reader have leaked, revealing a design with rounded corners and a relocated power button. Amazon has not officially confirmed these details, but the device is expected to be announced soon. This comes after the recent leak of visuals for the new Fire TV Stick 4K, and now another Amazon device, the Kindle, is set to be revealed before its official launch. The German media outlet WinFuture published a series of images on September 28, presented as official for the next-generation e-reader, which it identifies as the 12th generation. At this stage, Amazon has not confirmed the details, and WinFuture notes that it only has these visuals, without any information on price or technical specifications. However, the images provide enough detail to highlight two noticeable changes: the shape of the screen and the position of the power button. One of the most visible changes is the adoption of slightly rounded corners on the E Ink screen, similar to those found on smartphones. Previous Kindle models featured "perfectly angular" panels, according to WinFuture. The second change is the relocation of the power button from the bottom of the device to the upper part of the right side. This shift is considered significant for usability, as the current placement often leads to accidental presses during reading, a common annoyance for users. The visuals also suggest that the screen may be offered in two variants, one of which would be less recessed in the housing. However, this interpretation is based solely on the images and remains speculative. In terms of hardware, WinFuture offers no confirmed details. It speculates that Amazon might once again focus on improving the screen brightness, potentially including front lighting and a six-inch diagonal size, but these are just hypotheses and not confirmed leaks. The leaked visuals show a standard black version of the Kindle, as well as green, light blue, and purple color options. However, WinFuture cautions that the actual number of colors available may differ. Additionally, Amazon appears to be preparing a new Kindle Kids edition, which would likely differ from the standard model only by a provided case and possibly a longer warranty. No price has been disclosed, and Amazon has not confirmed a release date. Until the official announcement, the characteristics, price, and availability of the new Kindle remain unknown.
