Gaikai's Dave Perry had told press that the service is already feature complete and should be ready to launch to the public in mid-December.
Speaking to VG247, Perry said that the service would not go through a public beta launch period for testing, instead becoming available to the public as a finished product.
"We said we'd be done by the end of September, and we are," said Perry.
"We're feature complete. You see it running from Dallas (at GDC Online). That's the experience that people are gonna have. So the problem is we have not had the mass market real gamers come and play this. We've had publishers playing, but we haven't had real gamers."
"The minute that announcement comes out of who we're gonna partner with, we'll start sending out invites immediately. And we're gonna do that for 60 days. So we are 60 days from the start of those invites to launch," he explained.
"So that means, at some point in December - probably mid-December - we will be live. There will be no 'you're in a beta.' It'll just be 'go ahead and play.'"
In June this year, Gaikai confirmed that EA had signed an agreement which would give them to the rights to stream many of the publisher's titles via the service.
Currently, they're the only publisher to have publicly signed such a deal, but Gaikai's chief technical officer Andrew Gault told GamesIndustry.bizshortly afterwards that he expects to have all major publishers signed up by the year's end.
