I am absolutely not hyped for a game that will undoubtedly be more about showing off Valve's VR technology than telling a compelling story with good gameplay.
It's not Half Life 3, Valve still isn't going to admit that that is never happening. This feels more like using the Half Life brand to sell copies of their VR tech more than a game developer coming out of a decade long hiatus to reveal the next masterpiece entry of a legendary game series.
It's a full title mate, not a tech demo.
