Will there be a half-life 3?

Question

I wonder..

Answer 1

Most likely, there have been leaked concept art of the game.

Answer 2

Maybe, but valve says they stopped making HL games because gordon freeman's voice actor died even though he only talked 1 time in the series, but its a 50% chance that they find a new voice actor, cross your fingers while you wait. also remember that it might not be HL3 it might be HL2 episode 3
