It seems that evil antagonist GlaDOS from Portal is v3.11, which coincidentally matches March 11th, when boss Gabe Newell is at the GDC.
The plot thickens... but only a little. Valve's Newell will be receiving his Pioneer Award at next week's Games Developer Conference in San Franciso March 11th, which is when the Portal 2 news shall strike say ardent believers.
Portal game code is also said to contain the very first Portal 2 artwork as fans continue to pillage the secrets hidden by Valve developers with the latest PC patch. Would a Portal sequel slap a grin on your videogamer chops?
