| In an official My Nintendo news post about the upcoming Mario Kart World Open Series being held from 5th March to 25th March, Nintendo might have accidentally spoiled a major content update that's planned for this year's MAR10 Day. One of the screenshots, meant to show off the rules of the "Knockout Tour" portion of the tournament, hides an explosive piece of evidence that eagle-eyed fans have spotted, hinting towards the return of the Bob-omb Blast battle mode from Double Dash and Mario Kart 8 Deluxe. If you look closely at the menu icon for "Battle" in the screenshot (which still hasn't been taken down at the time of writing), a Bob-omb can be seen alongside a balloon and a coin, which represent the other two modes in the game, Balloon Battle and Coin Rush. The Bob-omb isn't present in the current version of the game, so either someone at Nintendo made a mistake, or this is an intentional, easy-to-miss tease for more exciting things to come in Mario Kart World. |
