Will Half-Life 3 come out during Gabe Newell's lifetime?
When Half-Life was released in 1998 it was quickly hailed as one of the greatest first person shooters of all time and its sequel Half-Life 2's release in 2004 was no less successful, spawning two expansions in the form of Half-Life 2: Episode One and Half-Life 2: Episode Two which ended on a cliffhanger in 2007. A third installment was promised but never materialize and since then Half-Life 3 has become something of a running joke in the PC gaming community.
Gabe Newell is the co-founder and president of the Valve Corperation. He's in his mid-fifties and apart from his weight appears to be in fair health.
Given the sheer value of the Half-Life franchise it's reasonable to assume that Half-Life 3 will be released at some point in the future but at present it seems that Valve is significantly more interested in pursuing other projects.
Will Half-Life 3 come out while Gabe Newell is alive?
Question resolves positive if Half-Life 3 (or an equivalent continuation of the series under a different title) releases before Gabe Newell's Death.
Metaculus help: Predicting
Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.
The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available. With tachyons you'll even be able to go back in time and backdate your prediction to maximize your points.
The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.
Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Metaculus help: Community Stats
Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.
When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
