price point being a major concern of course , especiallyafter the last year. but to my understanding their "unbreakable", rollable, foldable display doesn't cost much more that the glass displays it could replace and the difference is mainly volume. their display is also a bit brighter because it has less layers in front of the display.
the current generation the are able to produce is a 6 inch 32 gray scale pearl type capacitive touch display. they can produce it in volume and they are even marketing it a bit to other OEMs for use in traditional non-bendy readers for its durability. hence the ball drop test video etc.
I know there was some interest in it from several vendors but I do not know if anything has gone past discussions with any of them. PV themselves were really on the verge of retail production of the Readius when the financial troubles hit them, a result of the major investor being involved in a ponzi scheme and not any actual trouble at PV. They had already test run several hundred through production. They have built functioning prototypes of not only the one depicted in the video i linked to previously but also of the "dream device" depicted on their website
