The sharp eyes over at IGN have spotted what may be a juicy bit of news over on the Devil May Cry 4 fansite. If you click on the option to download a DMC4 widget, the site loads up an example picture which shows that the demo for the game will be hitting the Xbox 360 and Playstation 3 on January 31.
Of course, as IGN also points out, this could just be bad placeholder text for the widget example. But with the game hitting just a week into February it doesn't seem like too far a stretch for that demo date to be right.
