Yes, he confirmed the "private beta" will be released in August. Now, "private beta" should mean that it won't be ready for public released yet, but for testing purposes.
It would be something if this happen when he sad it will be, but i dont think so thins project is more and more sinking ship and will never see light of a day.
Perhaps im wrong but this is simple my point of view on the matter to many promises and to little was offered to see.
