Sales of Electronic Arts video games for older consoles have tailed off more quickly than expected, the publishing giant said yesterday. Blake Jorgensen, EAs chief financial officer, said there was a much sharper decline than anticipated in demand for current-generation software, as third quarter sales for EA games on Xbox 360 and PlayStation 3 dropped 35 percent against the same period the previous year. The unexpected dip caused a revenue shortfall for the publisher, but Jorgensen was optimistic about the future. He said that the downward trend on Xbox 360 and PS3 software was partially offset by positive next-gen results.
