Take a look at Blizzard's official website. Once you open it, it opens up a wallpaper. We all know that WWI is only days away. Blizzard loves to do these kind of things right before a game is announced. I remembered during the annoucement of WOW and SC2, they did something similar to this. People have been speculating that the new game announced at WWI could be D3. But from the looks of it, the wallpaper doesn't have any kind of D3 feel to it. Infact, it looks very SCish to me. Anyways, let the speculation begin!
