Sony is planning to step up its e-reader efforts today based on details from a new rumor. One of the most "trusted sources" for Sony Insider claimed both the Reader Pocket Edition and Touch Edition would get updates. Touch Edition upgrades would be the most dramatic; the new PRS-650 should add Wi-Fi and possibly 3G for the first time in a Sony device its size, while it and the Pocket Edition PRS-350 would be much more efficient and thinner; one could be less than 1cm (0.4 inches) thick.
