Which doesn't mean it won't end up being true. NMag's reported predictions range from the incredibly obvious (the controls will be similar to Excite Truck) to the only slightly obvious (powerslides and snaking will return) to the non-obvious but still unsurprising (online battle mode, Baby Peach and Baby Boo as characters).
Come on NMag ... if you're going to speculate, you might as well throw some really crazy stuff out there. Here, we'll get you started: Sonic will be a playable character, but he won't have a kart, he'll just run! Wart from Super Mario Bros. 2 will be featured in a boss race! On-track coins can be used to purchase Wii Shop points! Commenters, take it away.
