It was announced Thursday that Nintendo will soon begin installing WiFi kiosks in Gamestop and Best Buy stores for Nintendo DS Light owners to download movies trailers, and demo games. When a DS user goes near the kiosk they will be prompted for a download. Once the dual screen DS has been turned off the demo content will automatically be erased. Nintendo will also be adding voice chat to â€œMetroid Prime: Hunters,â€? that will be available March 20th. Users will only be able to jib jab before and after games, not during. The slimmer version of the DS, the DS-Lite, will go on sale in Japan next month.
