A leaked survey from Nintendo reveals how the upcoming retro game download service for Revolution could work - including the pricing structures and game catalogues!

The survey's details - which included mock-ups of how the Revolution's graphical user interface could look, details on how the retro games would be priced and which would be available have now spread across the net, giving fans the most in-depth look yet on how the service might look.

According to IGN, the game survey was a a private study and never intended for press. Zanthus, the marketing company hired by Nintendo to conduct this survey, commented that "our agreement with Nintendo stipulates that the content of this and other, similar surveys can't be released to the press. This agreement extends to our survey respondents. It is unfortunate some survey respondents have broken their agreement with us by posting select research stimuli."

The survey begins with a mockup showing the Revolution's main homepage screen which contains the options "Settings", "Memory Cards", "Parental Controls" and "Virtual Console". Selecting "Virtual Console" will apparently then lead you to a system select screen, with the NES, SNES and N64 available. Cube titles cannot be downloaded because, of course, they can be played on the Revolution by just popping in the game disc.

After selecting a console, the gamer then reaches a catalogue of available software that can be browsed through, with options to either buy or rent software available. While rentable games would presumably be deleted after a certain amount of time, games which are bought get stored permanently in a "My Library" folder, shown in the concept screens. It appears games are bought with points, similar to the Xbox Live architecture.

A subscription based package which allowed you to rent and play any game you wanted is - in the survey - set at $14.99 (about �8.50) for a month. Alternatively, NES titles are available to download for $2.99 while N64 titles cost the more expensive price of $19.99 (just over �11).

The part of the survey which will excite many Nintendo fans is the long list of software that - again, in the survey - are available for download. There's plenty of games from our Top 50 Poll in there, take a look:

An important reminder - while you shake off the fact that Goldeneye, Super Mario RPG, Sin & Punishment and many, many more excellant titles are in that list - all this information is still speculative, despite it coming originally from Nintendo for the process of creating the survey.

Nintendo have today issued a statement on the leaked details from the survey, stating that the company is "considering a variety of options for the virtual console service for our next console, code-named Revolution, although details have not been announced at this time. In our normal course of business, Nintendo conducts consumer research for many of our products with information and imagery that do not represent actual product specifics."

We'll keep you updated when more news on this surfaces, though in the meantime, how does the pricing/game list sound to you? Make your voices heard on the forums! To see the mockups of how the Revolution's menus might look, check out the IGN article here.
