I think the next reader will have larger screen, I cant see a reason to make a 6-inch reader without wi-fi and then one with wi-fi. It is not a huge cost to put in a wi-fi chip. I think that the 600 looks really nice, too bad I am a european,,, (anyone else who wants to vote in USA into the european union?
)
I am expecting sony to come out with a new top of the line reader, (i belive so because of the modelnumber 600 is lower than 700 which it is replacing) and then I just might motivate myself to take a trip over "the pond" and get me a reader
