Kotaku has managed to get its hands on a survey that details possible paid services for Sony PlayStation Network.  The survey, distributed by IPSOS Online Research, found its way to the media outlet by way of a reader.  It shows a tiered services setup for PSN offering premium items such as cloud storage for downloaded games, live chat, and free playable games from the original PlayStation and PSP-mini catalogues.  It also shows that Sony is considering a premium trials service offering one-hour access to full versions of PS3 games.  Prices for various tiers of service shown in the survey are $29.99 a year or $4.99 a month for low tier service to as high as $69.99 a year or $9.99 a month for full services.  Sony hasn’t responded to Kotaku’s inquiries on the survey.
