The gaming website has published images of a survey from market research firm IPSOS outlining a potential premium subscription to the online service. Current services such as online multiplayer gaming will remain free should package deals be introduced.
"Sony is considering offering a premium PlayStation Network subscription in the future. The subscription offering would provide new premium features you could choose to pay for and are in addition to the features currently available for free such as access to online multiplayer gaming (current features would remain free)," the questionnaire states.
Several payment plans were mentioned - three costing $69.99 (£43) a year or $9.99 (£6) a month, and one costing $4.99 (£3) a month and $29.99 (£18) a year.
Additional features including online music services, cloud storage and cross-game chat will be available to premium subscribers.
Sony is yet to make an official announcement on PSN subscription charges.
