Although Sony representatives were not available for comment the filing is certainly interesting. It is not completely clear what the device is capable of, but it could be intended to allow games that require dual analog controllers to by played on the PSP.
The recent announcement of a smaller PSP unit that features digital output should also be noted when thinking of the possibility of PS3 to PSP connectivity.
More updates when they surface.
