Nintendo is set to drop the price of its Nintendo DSi and DSi XL handheld consoles later this month, in the hope of providing greater incentive for consumers to purchase the hardware.From May 20, the suggested retail prices of the Nintendo DSi and the larger DSi XL will be $99.99 and $129.99 respectively, down from the current price marks of $149.99 and $169.99. The company said that the new prices provide "an easy option for parents who want to introduce younger kids to their first portable games."The Nintendo DSi models are similar to the original DS, but with an added camera and an online DSiWare store, from which users can download digital titles. DSiWare titles are also available to download from the Nintendo 3DS eShop.The DSi's successor, the Nintendo 3DS, saw its price reduced last year after suffering from underwhelming sales. It originally launched at the start of 2011, just over two years after the original DSi was released.
