YotaPhone's first-gen E Ink / LCD mobile phone started shipping in Europe only a few months ago, and the Russian company already revealed a new prototype. The main new feature in this new prototype is the 4.7" E Ink display - it now supports touch and can now be used for e-mails, SMS messages, browsing and much more. 

The 4.3" 720p LCD has been replaced by a larger display, a 5" Full-HD Super AMOLED display (the same one used by Samsung's Galaxy S4). Seems like this is a really good upgrade, and hopefully YotaPhone will be able to release this new phone soon.
