At Sony’s “See the Future” event, Braid developer Jonathan Blow announced that his puzzle game The Witness would be coming to the PlayStation 4, and would have exclusivity during the PS4’s launch.
This means the game will still be coming to PC, Xbox 360 and PlayStation 3 (and possibly Xbox 720?), but it’ll have a month or so of exclusivity.
A new trailer for the PS4 version was shown at the conference as well.
