'Whilst a superstitious number, this is nothing but good news for Nintendo as the release of the popular arcade racer Mario Kart 8 has boosted the sales of the Wii U by 666%, with the game also managing to shift over 1.2 million copies! The Wii U is now predicted to sell 4x what it was originally by the end of this year and as a fan of Nintendo consoles, I could not be happier. There seems to be a selection of fantastic first party published titles and of course Watch Dogs that are planning to be released by the end of this year and Mario Kart 8 could serve as a catalyst for the Wii U. This one single game could have a huge impact on the future of the console and potentially Nintendo!'
