I really think we'll be getting a Direct before the CoroCoro news. If we get any real info, why wouldn't they broadcast it via Direct, so everyone can see it at once? If they reveal it through CoroCoro, they know Japan will be the ones to get the information first. With some new Pokémon or NPCs, sure, but if this is gonna be our mascots? Our starters, perhaps? That seems like something they'd want to show everyone at the same time. That being said, if it does turn out we get a Direct or some other kind of YouTube announcement, I feel the CoroCoro issue will either just reiterate the information, or just add some minor info such as a small overworld map illustration. I think the most they would add would be protagonist art, but I remember waiting a long time for the X&Y protags to be given official art, so we may have to wait a while for these, too.
