Hmm, possible vague Half Life reference already in the game, and the Portal Gun is supposedly coming out in 1.3. 1.3 contains 3, there are 3 main Valve games, (Half-Life, Portal, Team Fortress.) each doesn't have a third main game in the series... 3*3= 9, 9/1.3= 6.923.... third digit after the decimal is 3.... HL3 CONFIRMED!!!!!!!!!!!!!
