Half Life 3 finally confirmed? Or is Valve trolling us for GDC 2015? (Thief gameplay/commentary)

At this years Games Developer Conference in San Francisco Valve has a panel lined up that will be all about 'Physics for Programmers'. It will happen on the 3rd of March (3.3.2015) at 3 pm! Enough 3's in and around this event to get the internet one more time very excited about Half Life 3! Or is it maybe all about Team Fortress 3, Portal 3 or Left 4 Dead 3? Or is Gabe Newell just trolling us? What do you think?
