The Sony 300 will hit at a price point of $199. It will read PDFs via reflow, which has been spotty at best when used with RPG products (I have current Sony reader qith reflow and generally have not been pleased with the results). It does not appear to have any expansion memory like an SD card and it is indicated that it will hold 350 books - I doubt that is 360 books in PDF format.
The Sony 600 has SD and Memory Stick Duo slots for expansion, a touch screen, a stylus and the ability to take notes. It will have a price point of $299 (same as the kindle2). While it might be a real competition to Amazon as an ebook reader, as a PDF reader the DX will probable still be the better choice, especially for gamers.
