It's entirely possible, they introduced item-time based evolutions the same time they introduced location evolutions. Really, to play devil's advocate, getting a second form is not out of the question, especially considering it's not the first time forms have been split up in reveal times (Deoxys for instance).But, it sort of is. . .I'll admit, there's a lot of things no one saw coming. Mega Evolutions for one, were a prime example. But I HIGHLY doubt, they're going to reveal to us a new Evo method. ESPECIALLY, if the next and final issure of CoroCoro, before the release, is going to show a few new pokes and the Fairy Type chart. We'd have some headline saying. . . "More Unforseen news sure to blow your mind" like we got last month. I don't see it happening. If you ask me.
