That's a list of what people say they want to watch. The sales guesses are how much people (who post in the 2ch sales thread and thus probably follow sales data quite closely) think shows will sell, regardless of what the individual guessing likes (though it may cause slight bias). They're trying to do two different things, and asking different people.
I mean, Chihayafuru 2 being first would already completely invalidate the poll as an accurate predictor of success, if that's what it were trying to be. I love the show but it's going to sell terribly just like season one.
