Hopefully Amazon will greatly improve the PW screen light system or at least offer a comparable model without the light.

My guess is that Amazon will claim an improved screen, even if it is mostly marketing BS which Amazon is so good at (historically speaking). But since they have so much of the market share in the USA, if not the world, I really don't expect much in terms of real improvements or advancements in the eInk line of readers. There just isn't much competition to justify the R&D. So I suspect this will be a year of lackluster improvements or advancements. They will most likely put much more effort into the Fire line of tablets since that is where they have a huge amount of competition.
