I booked BWV 1 bd. standard view during the Epcot Food and Wine Festival the first day I could at 11 months. The F&W is a busy time of year at BWV and the std. views go fast - there aren't all many of them. I know that at the 7 month mark, they were pretty much booked. BCV books up fast, too.
At less busy times, you probably wouldn't have as much of a problem, depending on resort. The smaller resorts fill faster. OKW and SSR are much larger. WLV is the smallest. But you never know, sometimes you'll just get lucky.
