284w ago - Panajev2001a posted on NeoGAF (linked above) that Sony was recently granted a patent for what many think could be the next PSP or PSP phone. The patent is for a 'hand-held device with touchscreen and digital tactile pixels'.
The patent application states that the device could be used as a "game device, phone, portable media player, email device, Web browser device or navigation device."
Another patent was granted for a "data-transfer using hand-held device." The device would be able to "recognize a remote device from a signal generated by the remote device detector, recognize a gesture from a signal generated by the case motion sensor as a result of motion of the case; and transfer a file with the file transfer device from the memory to the remote device or vice versa in response to recognition of the gesture."
