I know Sony said they weren't going to compete on price... but what exactly are they competing on? If you are going to charge a premium over the best selling devices (Kindle and Nook in the US I presume), then it better have something going for it... and I am afraid for Sony that I just don't see a touch screen being that thing (I think wireless and ebook store integration is a bigger deal for people who want something more than a basic reader).
Ironically, the pocket edition again might be the star of the ball. While still a big step up in price from where the PRS-300 is selling, it still leaves it the cheapest 5" ereader with an e-Ink screen (I assume that this all means that the PRS-300 is being discontinued).
A few other questions.
1. Will they all have fixed epub formatting?
2. Will they still support LRF?
Final thought, Sony might think it is too early in the game for low pricing, but I disagree, Amazon and B&N both are competing on price. I think Sony's biggest problem is that they are essentially operating as a hardware company, not a media company.
