Got this off Lik sang

Each title will cost between 500 and 1,000, which converts to about US$ 4.50 to US$ 8.99, or 3.49 to 6.99 Euro. Apparently this relates only to entirely new and more simple game releases however, as Satoru Iwata explained idea of creating low-scale titles which startup in just three seconds, and "put an end to turning games into big titles -- like taking simple game concepts, just adding modes and selling for 5800 yen". Whether or not these prices will also apply to downloading NES, SNES, N64, Genesis and TurboGrafx games or not remains to be seen though.
