There's a slick trailer on the main page of their new reader, too.

No SD slot, I think it'll have 16gb built-in instead. But there's Bluetooth in addition to wifi on the specs page. From the video, it shows the reader interfacing with a desktop app, so you can upload and manage PDFs directly. Also looks like an easier to access thumbnails page to quickly find the page you want. And of course, a higher resolution 1650 × 2200 screen. And I also noticed the screen is flush with the bezel? That will make writing near the edge easier.
