Army of Two lead designer Chris Ferriera says that as much as EA Montreal would love to do a demo, they sort of need to concentrate on the game instead.
Asked when we might see one, he told Eurogamer: "Not prior to release. I don't know if there'll be something later, but the thing is given our release date [15th November for PS3 and Xbox 360 in the US and Europe] and where we're at, we'd rather focus on this rather than taking engineers off and having them do a demo."
Ferriera also refused to be drawn on whether we'd see more players supported in future.
"I can't talk about any expandability beyond the two-player co-op. I'm not allowed to talk about that right now," he said, describing two players as "an easy entry point" for the company's co-op approach.
As to whether that rules out an Army of Four or Army of Sixteen further down the line, he joked: "I can neither confirm nor deny the existence of such numbers of players."
