While this should certainly be regarded as rumour, it appears as though Sony has been seeking public feedback on a number of different features which could potentially be making their way into the PSP2.
The survey, sent to Kotaku by a reader, asks participants to rank a selection of features from least to most desirable. From this list it would appear Sony is looking into features such as a smaller footprint but similarly sized screen, social networking, keyboard, Bluetooth, touch screen, a hard drive, a keyboard and an e-comic/book download service.
This could well turn out to be bogus, but interesting nonetheless. For more on the PSP2, specifically the features we feel should be included check out our recent feature.
