The Quantic Dream founder told GamesIndustry.biz that the studio's first post-Beyond game is already in development.
"I actually have probably my next three games in mind," he said. "Although I'm full speed on Beyond, I know what I'm doing after it because it's already in development, and I know what I'm doing after that and it probably after that.
"I keep thinking all the time, all the time I'm working. And it gives time to ideas really to evolve and to come to a moment where they're ready to be written.
"It's very important because when you start working on a project, you need to find that this is a good idea, not just for a week or a month but for years," Cage added. "You need to be sure that by the time you release the title it won't be like 200 other titles doing exactly the same thing in the same way.
"You need to make sure that you anticipated the evolution of technology in the right way because if you went too far you can't make the game, but if you went too low it will face competition. So all these are very challenging decisions to make."
Cage recently said that the Beyond release date is still scheduled for 2013 and will be announced "soon".
He also said he "can't wait to see what can be done with PlayStation 4" - the studio is rumoured to be working on a title codenamed Singularity for Sony's new console.
