Sony may be testing the waters of public opinion on the direction of the next PlayStation Portable, surveying gamers on a host of new hardware and software features for a possible PSP2.

Kotaku reader Charlie forwarded us details on the survey, which asks a the participant to rank a suite of currently unavailable features from least to most desirable. Some of the more interesting technical aspects it looks like Sony is looking into are things like touchscreen functionality, built-in GPS features, Bluetooth wireless support and internal data storage.

Most of that we’ve heard in rumour form at one point or another. Possible features we have heard less conjecture about include services like an “e-comic/book download” via the PlayStation Network and social networking functions for the PSP, including Home support.

The survey asked about possible PSP features including, but not limited to:

• Was smaller, yet retained most of the current PSP’s screen size
• Offered social networking functionality on the XMB
• Included a keyboard for easer internet browsing and communication
• Offered Bluetooth wireless support for easy pairing with other devices
• Had a touch screen
• Had an improved screen for more dynamic graphic displays
• Offered the ability to find others near you who want to connect for online gaming
• Offered an e-comic/book download service through the PlayStation Network
• Included a hard drive for memory storage

We’re checking in with other sources to see if there’s any truth to these feature adds, but expect that much of this fall under speculation.
