They don't need to close the gap. Xbox Series is a benchmark for their development studios to optimize the game for, and a marketing system to show that the best place to play is Xbox. But the actual important numbers are game sales and game pass subscriptions. Which is why they release their games on PC.Question is, can they close the gap any further... PS5 is a runaway train relying largely on brand name recognition at the moment. If MS can keep up the momentum they currently have this gen then the console race may be a lot closer than most were expecting.
