That date may not work or the whole world, but then again, when the game is set in a patriotic society, that holiday sounds a bit fitting. Also, it's common for a demo to not be 100% perfect (even the one for Arkham City has some noteable glitches). But for the most part, Infinite's demo is one of the longest by almost 15 or 20 minutes long, and like Pauolo said, they have shown this more than once before to the press, attendees, and a couple lucky fans.
