A keen-eyed Dota 2 player, touring the offices as part of The International 3 tournament, took a snap of an internal changelog that apparently lists both Left 4 Dead 3 and Source 2 as current projects. The below photo compliments a similar 'leak' via internal Valve documentation in June, although we have not verified the validity of either.
While co-founder Gabe Newell has been open (but unspecific) about Valve's work on a next-gen game engine, development on Left 4 Dead 3 has yet to be confirmed.
But Yet Still NO HalfLife 3 WTF Valve what's your guys problem give the people what we want and we will shut up already!
No release dates or any other information was given so what do you think?
