Both models are expected to be IPX8 waterproof like the original Kindle Paperwhite, as well as offer a flush-front design and have narrower sides and top bezels. They will also have an adjustable warm light much like the Kindle Oasis currently exclusively offers.  The Kindle Paperwhite Signature Edition should stand out from the other Paperwhite too thanks to an increase in storage, going up to 32GB, as well as wireless charging and auto-adjusting light sensors that change screen brightness depending on where you’re reading it. If the Canadian listing is accurate, the new Kindle Paperwhite will cost about $117 while the Paperwhite Signature Edition will cost about $165. We won’t know for certain until September 28th but it all sounds very plausible and promising if you’re looking to buy a new eBook reader soon.
