I'm hoping it has real info on Sylveon regarding its type and evolution method, and some info on Mewtwo's new forme, stating how it changes, and if it's more physically or specially oriented.
And Xerneas and Yveltal's types.
Maybe if there will be a Fairy type they'd reveal it now or announce it on Smash and then go into detail with it on CoroCoro, with a Pokemon being used to showcase this new type on Smash, and then a Fairy type move and ability, along with the weaknesses/resistances in CoroCoro? I can easily see a worldwide announcement.
Also, all of the above going on Pokemon.com, since they are revealing new info relatively simultaeneously.
