Probably. Nintendo might have an ace up its sleeve, but my hunch would be that usually it's Zelda that gets the most praise, and it's only two years since the previous really notable entry in the series. Other Nintendo games also have a chance, but I wouldn't bet on it. Non-Nintendo surprises are also possible, but I wouldn't bet on them either. On the other hand, a good bunch of very high-profile releases for this year have already been announced, and I'm expecting one of them to be the GotY (whatever that's even supposed to mean).
