After the announcement of the price and launch date for Amy yesterday, many (including us) were perplexed as the title's pricing disparity. Specifically, the US version of the game was revealed to be 800 MS Points ($10) on Xbox Live Arcade, while the PSN version would cost $3 more at $12.99.

The reason lies in the nebulous nature of Microsoft Points, according to Lexis Numérique CEO José Sanchis. In the US, $10 will buy 800 MS Points. In Europe the cost is €10, or about $12.73. In other words, noted Sanchis, the prices of the PSN and XBLA versions are essentially equal in Europe, but the exchange rate creates a disparity in the US.

To rectify the situation, Lexis Numérique has set up a Facebook poll -- an app that requires a Facebook account and your permission, incidentally -- to determine whether Amy's US PSN price should remain at $12.99 or be reduced to $9.99, the same as its XBLA counterpart. There is, however, a catch: Should the community choose to lower the price -- which seems likely, given current poll results -- the PSN release will have to be delayed at least a week "because of logistic constraints" with Sony's platform. The poll closes January 9.
