Half-Life 3, Left 4 Dead 3 and the next-gen Source 2 engine teased on Valve's Project Tracker

So, Valve Time have gone elbows deep into project management and bug tracking software, Jira, finding evidence of multiple internal projects at Valve. This includes Half-Life 3, Left 4 Dead 3 and Source 2, as well as many other games.

Valve left a metaphorical window open to Jira, which allowed people to access Valve's internal tickets, but were quick to shut it down of course - Valve Time, were able to turn on Bullet Time, and save some of this information for us to all get lady boners over. There's evidence for Half-Life 3 which includes a mailing list of 42 people, but Valve have given the HL3 project around 300 people to get down and dirty with.

Left 4 Dead 3 is mentioned, which suggests a third outing in the Left 4 Dead franchise is in development. The next nugget is Source 2. We know this is in development, and I've theorised that Valve will unveil Source 2 on their Steam Box, along with Half-Life 3, Left 4 Dead 3 and other games. Check out Valve Time's post for more information.
