what are you talking about? MS is a TRILLION dollar company, of course they have much more money than Sony and the CEO of MS even confirmed that they have tons of money for Xbox:
Phil Spencer says the next Xbox is supported by MS leadership and they can "stay agile" with the planned pricing for the console.

MS has 136.6 billion in CASH:
Several companies, including Microsoft, Berkshire Hathaway, Alphabet and Apple are sitting on more than $100 billion dollars of cash, which is leading some on Wall Street to question why America's largest companies aren't spending.

so, if the CEO and CFO say: Xbox is important to us and we are willing to invest as much as possible, then it's easily possible, because MS has tons of money, as you can see.
It's all about being the new Netflix of gaming. Just look at how much money Netflix invested, or in the past Amazoon invsted, or Uber, AirBnB etc.
Now the problem with sony is, that they simply don't have the money, just look at the recent earnings report:
Weak sales in electronic products and gaming drag profit down amid lockdowns

Now, if the gaming division is the ONLY division at the Sony Group that generates profit.... then where does the money come from? how can they invest and stop focussing on profit with the gaming division?
MS has Azure, Windows, Office 365 etc. they can easily offset the investments in the gaming division, they want to become the netflix of gaming and they have easily the money to be there.. but sony? how? where would they get the money from? their gaming division has to be profitable from day one.. especially now considering how corona disrupts their movie industry and their smartphone industry.
