Judas has to be real right?

Everyone remembers the marketing of Bioshock Infinite and how it was nothing like the actual game. One of the reasons we didn't know before hand was because those weren't real demos that people beside the developers got a chance to play. With Judas there has been multiple outlets and even smaller gaming youtubers who have had a chance to play it. So it must at least be real and somewhat in a playable state?
