"I'm getting concerned about Sony; the PlayStation 3 is losing a bit of momentum and they don't make it easy for me to support the platform," Kotick explained. "It's expensive to develop for the console, and the Wii and the Xbox are just selling better."
"Games generate a better return on invested capital on the Xbox than on the PlayStation," said Kotick. He states that Call of Duty and Guitar Hero publisher Activision paid Sony over $500 million last year in royalties and other costs, quipping that the figure "probably still worked out at 400 per cent of the profit they made."
"They have to cut the price, because if they don't, the attach rates are likely to slow. If we are being realistic, we might have to stop supporting Sony," he said. "When we look at 2010 and 2011, we might want to consider if we support the console - and the PSP too."
Kotick adds that a new physical interface "could be ideal." Sony announced the motion-sensing camera PlayStation Motion Controller at E3 this year, arriving Spring 2010.
