Thoughts may be that manufacturers like Sony, netronix, irex technologies, and Jinke Electronics might copy a great deal from the prototypes created by e-ink; definately improve on design, and maybe come up with few other tricks on their sleeves.
I'm not a very 'bluetooth' fan, but it might be that the next gen will have bluetooth; maybe good if it would support bluetooth keyboards.
Also, we don't yet know what 'fast display update speed' means..
