Stadium design causing more home runs?

In a recent article at the New York Daily News, they state that the design of the new Yankees Stadium is the reason for an abnormal amount of home runs being hit in the stadium.
Accuweather.com states, "The wall structure is slightly different than the old park. The main difference involves curvature. The gentle curve from right field to center field seen in original Yankee Stadium has largely been eliminated at the new stadium. This is due in large part to the presence of a manual scoreboard embedded within the wall. Losing this curvature has resulted in a right field that is shorter by four-to-five feet on average, but up to nine feet in spots."
