The official website for The Witcher 3: Wild Hunt has a mysterious countdown pointing to what I assume to be some sort of reveal on Wednesday, August 14, 2013. Currently, the clock has just over one day remaining, indicating the announcement will be made at 11:00am Pacific (2:00pm Eastern).
Unfortunately, there's no real clues in the teaser aside from the URL which ends in "/killingmonsters," and a "download goodies" button which downloads a folder full of wallpapers and music from the previously released trailers.
So what do you think the teaser will be? Whatever it is, I just hope it isn't a teaser for something at Gamescom which is just around the corner. If you are going to have a countdown, make it worth my time.
