Ran across one site which posted an item claiming an anonymous source within Kobo stated the Kobo NoName is going to be using an eInk Kaleido colour display panel. This would match with other devices being released using that panel.
It looked rather similar to Nate Hoffelder's
The Digital Reader blog where he mentions the Nia and hopes that it would have an eInk Kaleido though it is not mentioned in the electronic label. Other than the unnamed source, of course.
