As Pretty Little Liars showrunner Marlene King recently tweeted, plans for the Season 3 winter finale are already underway. Is it safe to assume that Season 4 is a sure thing? ABC Family hasn’t officially renewed PLL for a fourth season yet, but that's mostly because it’s a little too early in the season for renewals. Based on ratings alone, PLL continues to soar, especially among advertiser-friendly 18-34 year-old women, where Season 3 averaged a 2.8 rating. On average, Season 3 had an audience of 3 million viewers per episode, according to Zap2It. While it seems like a no-brainer to renew (and in all likelihood, ABC Family definitely will), some of the cast and crew have hinted that Season 4 could be the final season. Back in 2011, executive producer Oliver Goldstick told The Hollywood Reporter, “Maybe some series aren’t meant to go beyond four seasons … This could be a four-season show.” And earlier this year, Ashley Benson (Hanna) told Teen Vogue that producers were talking about ending PLL after four seasons and making a feature film.
Whether or not PLL Season 4 will be the final season, we would bet that Season 4 is going to happen. So don’t fret just yet!
