Many other things from this interview (which already have threads), but I felt this one deserves its own topic as well:

Where does that leave the prospect of more Xbox games coming to non-Xbox consoles? Spencer told me that "it doesn't feel sustainable" to consider Xbox games on a case by case basis for Switch and said, "In order to really support it, I would want a full Xbox ecosystem somewhere. And that probably means things like Live and Game Pass and stuff."
He said something similar in July during an interview with GameStar, though the answer has changed slightly. Back then he said that "the other competitive platforms aren't really that interested in having a full Xbox experience on their hardware." I cited that answer to him and asked if it was still the case with Sony and Nintendo. "I don't want to speak for them," he said. "I think they should probably answer."
