Valve's name has been added to the official list of E3 2012 exhibitors. They'll be located in PMR501B which is a private room where an appointment is required to enter. Ok folks, I know I'm singing the same old song here, but could this be the year we catch a glimpse of Valve's next Half-Life? There's been an influx in chatter and rumors since 2011 about the next HL game. It kicked off with this tweet showing a Valve employee trolling around in a Half-Life 3 shirt at a local game developers meetup. And then to add some fuel to the fire, we heard from OXM that a US-based voice actor was recording some lines for "Half-Life: Episode 3"... But before all of that, PC Gamer's "Spy" also suggested that we might be seeing Gordon Freeman again soon. Some will suggest that Valve is attending E3 2012 to show off Dota 2 and/or CS:GO. But would Valve really have a private meeting room to showcase two games that are very much in a public beta? I certainly don't think so. And E3 is an expensive venue for exhibitors, so for them to book a room to only show some Portal 2 DLC or L4D DLC seems very unlikely as well. And then the last possibility of what we could see is an entirely new IP from Valve, something that's been rumored for awhile now. Last year, a game journalist was given information at EA's Spring Conference about how Valve was developing a new IP. Around that same time, a gamer by the name of PoliticalGamer took a tour of Valve's offices and found some unseen & unknown concept art on the walls. Then a few months later, references to an unknown game were found in Dota 2's code. Lastly, some of this concept art was found on Peter Konig's portfolio website - [concise album], linking the "SOB" file references with the mysterious concept art. So what do you think? What is Valve going to show us at E3? GDC 2012 also starts this coming Monday, and it appears that Valve will have a rather large presence at that event as well, so maybe we'll get an early taste of things to come. As always, stay tuned!
