"Wrath of the Lamb," the enormous expansion to The Binding of Isaac, has been assigned a release date even more specific than the "late May" window it previously had: it'll be on Steam May 28, creator Edmund McMillen told Joystiq.

McMillen also reiterated his claim that Wrath will be the sole expansion for Isaac. "Development for Super Meat Boy: The Game has started full time and once it's moving I won't be looking back!" In the meantime, you should look up - at the new, terrifying trailer for Wrath of the Lamb.
