People have been predicting the comeback of the Western for years.
There have been some notable hits on both the big and small screen: Django Unchained, HBO's Deadwood, and the True Grit remake, among others. While the pulp Western novel is buried in a dusty hilltop cemetery in Wyoming, there have been some excellent more literary takes on the genre, including Philipp Meyer's The Son and, going further back, Larry McMurtry's Lonesome Dove series. You also can't ignore the impact of the massively popular game Red Dead Redemption. But somehow this trickle of new Westerns has never become anything more than that.
My theory is that, in fact, the Western is back ... but as the Zombie genre. (ZomGen? Zomre?)
