PSPWorld has details of the upcoming Grffin products designed for the PSP.

The first is an FM radio tuner that attaches to the bottom of the PSP. From the photos its looks like it has been designed to complement the PSP styling, although it does add a little to the overall size of the PSP.

There is also an FM radio tuner that pugs into the headphone socket and is similar in function the standard PSP headphone control device, only with a built in FM tuner as well. This looks the better option to me, and would enable you to listen to the radio while the PSP is tucked safely away in its protective case.

Griffin are also introducing a headphone splitter, meaning that cosy nights in in front of the PSP with your loved one no longer needs to be a solo affair.
