An interesting survey suggests that Sony may be considering implementing a selection of different subscription levels for PlayStation Plus, each offering different perks and incentives. Free day-one releases and Call Of Duty: Elite subscription have been suggested as possible rewards.
According to IGN, Sony has been polling PS Plus customers to see what extra rewards they'd like to see from their subscription service. The survey presents a number of differently-priced tiers and asks participants to choose which they'd prefer - many of which include free, day-one, full versions of PS3 games rather than just PSN and PSOne releases.
For example, one potential option would cost users $7.99 per month, providing 61 'A' grade games per year including one free full PS3 game. A $10 option would provide 80 'B' to 'C' grade games per year, though ten full PS3 titles would be made available on an annual basis (providing they're over a year old). Other potential plans include free Call Of Duty: Elite subscriptions. Essentially, many of these plans would function like an all-inclusive game rental service on top of providing discounts and early access to trials.
Of course, this is all in the hypothetical brainstorming stages at the moment, but it's an interesting statement of intent. Could Sony be looking to offer a range of paid PSN subscriptions to supplement regular free membership and PS Plus? We'll have to wait and see.
