Marvelous Entertainment have announced that both the 360 and PS3 versions of No More Heroes: Heroes Paradise, have been delayed. The Xbox 360 * PS3 HD remake was originally scheduled for release on February 25th, but will now arrive some time in April.
The company cited the old "various circumstances" on the official website:
I suspect the delay is due to Grasshoppers Manufacture stepping in for quality control reasons, making sure that game releases in tip top condition with no technical issues. As well as making sure all the new options like Very Sweet Mode and Rebout Mode meet their requirements. The whip has been cracked on Feel Plus, but It will be for the benefit of the game.
