Consider the following: Through carefully placed hints and tips, as well as some clever marketing and masking on their part, Valve teases that Episode 3 or possibly Half Life 3 may be upcoming. Through some clever sleuthing, denizens of the internet have drawn a link between the hazy “hacked” Portal 2 information and drawn a handful of conclusions.
