Here’s some interesting answers from Gabe Newell and Valve from the reddit AMA

Gabe Newell and others at Valve are doing a reddit ‘Ask me anything’ and I have compiled a list of some good stuff to read. This took a while to gather, so I hope you find it interesting.

You can see my own personal questions here, which at time of writing have not been answered.

Update: And it's over, my questions didn't get answered.

These first few are from this post.
What is the status of Half Life 3/Half Life 2 Episode 3?

GabeThe number 3 must not be said.

Is Valve still working on any fully-fledged single player games?

GabeYes

An unidentified anonymous source at Valve has said that Half Life 3 has been cancelled. Is that source legitimate?

GabeI personally believe all unidentified anonymous sources on the Internet.

Any chance of a new IP that takes place in the half-life/portal universe? I feel like there's a lot of story left to be explored there. Thanks! (source)

GabeYep.

Does Valve plan on doing anything with Source 2 in the coming years? If so, what? (source)

GabeWe are continuing to use Source 2 as our primary game development environment. Aside from moving Dota 2 to the engine recently, we are are using it as the foundation of some unannounced products. We would like to have everyone working on games here at Valve to eventually be using the same engine. We also intend to continue to make the Source 2 engine work available to the broad developer community as we go, and to make it available free of charge.

If you could go back in time, what would you change about Steam?(source)

GabeBiggest issue has been how we structured support.

This question is related to the above and has a pretty good answer:
Does Valve have any plans on making customer support better? And did you ever think of making it into live support?(source)

GabeYes! We are continuing to work on improving support.
Since the last AMA, we've introduced refunds on Steam, we've grown our Support staff by roughly 5x, and we've shipped a new help site and ticketing system that makes it easier to get help. We've also greatly reduced response times on most types of support tickets and we think we've improved the quality of responses.
We definitely don't think we're done though. We still need to further improve response times and we are continually working to improve the quality of our responses. We're also working on adding more support staff in regions around the world to offer better native language support and improve response times in various regions.

Gabe also said they are considering putting in an option to allow Steam users to disable event pop-ups (source).

Gabe, what is TF2 in Valve's eyes? Do you plan to improve the state of the game in 2017? Will there be more focus on the game by Valve? (source)

DRiller_ValveTF2 has millions of unique players per month, and the team is staffed by a group of people that love and play the game. We're committed to supporting and growing TF2 with new features, content, and player experiences.

We're currently working on our next major update, which features a new campaign, the Pyro class pack, matchmaking improvements/features, and lots of game balancing improvements.

When asked about Counter-Strike Global Offensive: (source)

ido_valveAs far as a roadmap is concerned, our priorities for 2017 are to replace the UI with Panorama, to make CS:GO available in more territories where a lot of Counter-Strike fans don't have easy access to it (like China), and anti-cheat. Of course, we're also planning on continuing to ship bug fixes and new features throughout the year, as in the past.

We plan to continue updating every week or two. As for Operations, there's no set schedule. We weigh that work relative to other work we could choose to focus on and other recent work seemed better for the product. For example, at the end of 2016 we chose to focus on shipping Inferno, improving spatial audio via HRTF, joinable public lobbies, and some long-term work that hasn't shipped yet.

We haven't considered community managers because in general we prefer to communicate by shipping game updates. We try to avoid disrupting conversations happening in the community, which is why we tend to be quiet a lot of the time. But we do weigh in when we have useful information to help those conversations along.

When asked about what led Valve towards open standards: (source)

Programmer_JoeOpen standards are what got the PC to where it is, and we think they'll continue to be important going forward. It's a big part of why we pushed Vulkan along. That's why we're working with Khronos on the VR standard.

That’s all for now, if I missed anything vitally important I will add it in later. It's possible another editor may add it in for me while I catch some zzz.

Apologies in advance for errors, as it's nearly midnight now for me and I need to sleep sometime. Article taken from GamingOnLinux.com.
