Nintendo has said they will spend around $200 million on Wii marketing campaigns in order to compete with the PS3 and Xbox360. The advertising campaign will be the biggest for Nintendo yet, with the first TV ads airing tomorrow (watch it here).

The $200 million, spent over the next 12 months, will generally be used for ads targeting the adult and non-gamer demographics.

Analysts from Deutsche Bank predict that Nintendo will sell 1,5 million Wii units in North America this year, compared to 2,3 million Xbox360 consoles and 500,000 PlayStation 3 consoles. Other analysts think that Nintendo will sell over 2 million Wiis this years, while the PS3 sales could reach as much as 1,5 million.
