I think a new Half Life game would be the perfect opportunity for Valve to showcase their virtual reality kit. So far there are no blockbuster VR games and the Half Life franchise (Portal included) has a history of being very innovative (e.g. HL2 using a physics engine for the narrative, HL1&2: story told through level design). There is a lot of potential to use immersive virtual reality to enhance the story telling.
