Well, well, well. Look who finally decided to show up to the party! Our ol' friend Gordon Freeman!! Just leaked was this piece of concept art from Half-Life 2: Episode 3.

Although not confirmed, this piece does seem to have a similar style to the recently released concept art from Valve:
In the future, everything is pointy and wants to kill you.
Someone smell an announcement coming on? Anyone think we'll be able to play this one by Christmas??
