The Playstation Portable is boosting its music playback capabilities with firmware 4.05. Nothing official yet, but there seems to be an added visualization while you’re playing music. The v4.05 firmware will certainly come soon, but what I’m really looking forward to is the implementation of a new Sony patent that puts “digital tactile pixels”on a portable device. The design came from the Sony Computer Entertainment, which is responsible for the PSP. Hope Sony announces more than the 4.05 firmware on E3.
