They didn't say that. According to this article, all that was said is that they're "next project (likely Elder Scrolls Online) is in currently in pre-production, but its at the stage where it requires the studio's full attention."

To me, this says they're current project is requires they're full attention at this time. Which sounds like they are saying that when this stage of the project is finished, they will start a new project. So, we could see an Elder Scrolls VI in the future. It's just there's no telling when exactly it will happen.
