Rumours are circulating this afternoon suggesting that the 360's exclusive downloadable content for IV may have slipped - and will not now be released this autumn as originally planned.

"Frankly, I don’t know," he told Eurogamer.net. "Rockstar are the people to ask for that."

Doesn't sound promising, does it? "I hope as a gamer, just like I’m sure you do as a gamer, the sooner the better,” he added. “I can’t wait for it," the big cheese added.

More soon.
