Mario games dominate Nintendo's console sales, with titles like Super Mario Bros. and Mario Kart being top-sellers. Pokemon is also a major player in Nintendo's success, with games like Red and Blue and Gold and Silver selling millions.

Nintendo has sold around 150 million Switch machines since the gadget's launch in March 2017. That makes it the third best-selling console in video game history, behind Sony's PlayStation 2 and the Nintendo DS. Nintendo estimates it has sold a colossal 1.3 billion games that run on the console.

The Mario-maker offered a sneak peek of its highly anticipated new console in January after a series of leaks, but the official detailed unveiling is set to take place Wednesday.
