Amazon will be releasing their new Kindle Paperwhite early Q2 2014. The new Paperwhite e-reader will have a high resolution 300 PPI display as opposed to the current model that has a 212 PPI. The prototype of the new Paperwhite has a screen that sits flush with the edge of the device and not recessed in, like the current model. It weighs less and has a matte-like glass screen to replace the plastic.
Amazon is upscaling the software for a better high resolution look as well as making a custom font that will be better for reading. There is no official release date or pricing for the new Kindle Paperwhite, but it will be available sometime Q2 of 2014.
