Mario Kart 8, announced during E3 last year, is the latest in Nintendo's long-running arcade racing series. This new installment includes a gravity-defying mechanic that lets racers ride along walls.
Last week, Nintendo had to slash financial forecasts in light of weak Wii U sales. Originally the company had projected Wii U sales to reach a total of 9 million from March 2013 to March 2014. Nintendo now anticipates Wii U shipments will reach 2.8 million in that timeframe.
