You can be absolutely sure he's coming back.
What I will say, though, if I can maybe speculate on another aspect, is that one thing the universities and industry don't do very well is build longer-term relationships. Many times relationships are formed on individuals; when people change companies or people change universities, that's lost, but if that relationship can be built over time, there can be in-kind contributions from gaming companies to universities in such areas as sharing of art assets or sharing of game engines. With Unreal, for example, there are relationships between companies and universities over the development of it.
It's a very complex problem. I would say that gaming companies tend to be extraordinarily protective of their IP, because it's not like it's a mine. The IP is everything, in many ways. Yes, the talent is of course important, but the development of the IP is essential, so it's a very finicky area when you're trying to understand how it can be used in a way that can be open source.
There are clearly open-source game engines and open-source tools that people use, and those are great, and in the modding community a company like Bethesda might release Skyrim, which allows open modding of that particular program. That's another issue—
