‘Hiruu’ pointed us to the official The Punisher game website which says that demo discs are now available:
Can’t wait to play the Punisher? Completely understandable. Get moving to a participating GameStop and EB Games location to get a Punisher demo disc with the purchase of an M rated product! Also, pre-order now and get a free Punisher t-shirt when you pick-up the game! Demo discs and t-shirts available while supplies last. Let the Punishment begin!
