Phil anticipates that the way games are "built and distributed" will continue to evolve - in order to meet "the pressure on the industry" to keep growing. Here's his full comment on this topic:
"I think as an industry right now, there's a lot of pressure on the industry... it's been growing for a long time, now people are looking for [new] ways to grow. Us as fans, as players of games, we just have to anticipate there's going to be more change in some of the traditional ways that games are built and distributed... that's going to change, it's going to change for all of us.
But, the end result has to be better games that more people can play. If we're not focused on that, I think we're focused on the wrong things. So, for us as Xbox: health of Xbox, health of our platform and our growing games - the most important things."
The Xbox boss does have a fair point here - although Sony hasn't moved towards bringing PlayStation games to Xbox yet, the Japanese firm is committed to bringing its games to PC, and even Nintendo Switch now with LEGO Horizon Adventures. At one stage that would have been unthinkable for Sony, so clearly, things are shifting and changing in the industry.
Anyway, the bottom line is that we can all anticipate more games to come to more systems in the future - even if they're built in-house at some of the industry's biggest platform holders.
