PC download service Steam will make three announcements in its bid to wrestle control of the living room from PS4 and Xbox One.Steam launched 'Big Picture' mode last year, which was a user-interface that made Steam games ideal for play on televisions and controllers. It worked but isn't a particularly accessible solution.But next week - starting with the first on Monday – Steam-owner Valve will make three further announcements designed to make the service more accessible in the living room. Putting it in a stronger position to combat big next-gen consoles: PS4 and Xbox One.For those fans craving for news on Half-Life 3, or Left4Dead 3 or Portal 3 or whatever the next game from Valve will be, I wouldn't necessarily get your hopes up. The three announcements are specifically around this living room concept.Unless, of course, this is the long-awaited Steam Box announcement. And Half-Life 3 is its exclusive blockbuster launch title. Now there's a thought.We'll know more once the timer on this site falls down to zero.http://www.mcvuk.com/news/read/steam...monday/0121460
