According to SonyInsider, Sony will launch a new touchscreen Walkman player at CES 2009.The player will have 16/32GB memory and Wi-Fi. The display will be a 3" Touchscreen AMOLED (WQVGA).
This is interesting news as Sony stated they will only develop OLEDs for TVs, not smaller panels (perhaps they will buy the panels from Samsung or CMEL?).
The player will include special YouTube support, direct connection to Amazon to purchase CDs and an FM radio.
