A quick reminder that just because one part of a leak is announced officially or otherwise proven true, does not mean that everything in the leak is accurate!
A good example of this was one of the leaks regarding Smash Brothers 4; it managed to get a few really odd characters like Wii Fit Trainer right, but also had a few other, wrong guesses with it. So, even if certain aspects of (insert whatever leak here) are true, still take the rest of the leak with a grain of salt, especially if the rest of the leak is really odd (the plot revolves around building your own league falls under this imo. A really odd thing to change up now, for sure, and one that would complicate things unnecessarily)!
