The article states that this is only a forecast.
"[They] analyzed the retailers’ store counts, recent financial data, online presences, prospects against direct competitors and precedents set by other large retailers that have downsized by shuttering locations. We then forecast how many stores each retailer will have to close this year to sharply increase its prospects financially, even if some of those location closings do not occur for several years. These forecasts were based on drops in same-store sales, drops in revenue, a review of direct competitors, Internet sales and the size of cuts at retailers in the same sector, if those were available."
I'm sure some will be closing this year. Hell they closed one in the mall near my house, but it's too soon to tell about other stores. If I were them I'd start looking for other work now though.
