Valve will continue its living room invasion by announcing three separate Steam related items, with the first announcement coming next week.
A teaser site mentions Valve's progress with the Big Picture mode on Steam and then alludes to the next step towards bringing Steam to the living room in 2014. Each announcement will come on different days with the first announcement's countdown ending on Monday, September 23rd at 1pm Eastern.
Based on the constant discussion around a Steam Box inevitably coming from Valve, their newest teaser site may begin the company's venture into the hardware space.
To add to the ambiguity of the teaser site, three separate circles encase different symbols. Since I never excelled in code decryption, maybe you will see something that points to a new console. If you feel optimistic, maybe even Half-Life 3.
