Earlier today, we told you about the Man of Steel homepage having a static video that you had to click on to get through to the site. The video has changed a few times, including sometime this evening to c934k200. More importantly, the Man of Steel Facebook fan page figured out that there’s a countdown hidden in the website’s source code. The section labeled “var deltaT =” has a number that gets smaller with every page refresh. If we assume the number is seconds, and we add the current number to the current time, we get 6PM PDT on Monday. It’s a good bet that is when the 3rd trailer will debut. It’s still unclear why the video keeps changing, so we’ll keep you updated. Click here for more of our coverage.
