Jonathan Blow has appeared on stage at Sony's event today, to talk about his upcoming Braid followup, The Witness, which is now a PlayStation 4 exclusive (confirming rumors we'd heard before that the title was going to be console-friendly, depending on "business things"). Blow described the first-person exploration puzzle title as "a game about epiphany, that instantaneous transition of the mind that takes you from confusion to understanding."

The Witness, said Blow, will have 25 hours of unique puzzles to play through, and the game's exclusivity will include the new console's "release window," so presumably the title's availability is open after that. Blow then showed off a quick video of the game, which looked about like what we've seen before, though perhaps with a few more bits of graphical flair thanks to the PS4's shiny new hardware. Stay tuned for more information on when the PS4, and The Witness, will be available to buy.
