Also, those games are selling into a vacuum because, ahem, in 2024 Sony has no games.
(No first party games, anyway.)
Maybe 2025 will be different.
What MS has been doing is spending today's (well, yesterday's) cash stash to buy future revenue because otherwise inflation would eat it up.
And going after Sony (and Nintendo) customers during the tail end of tbeir console generation is good opportunistic business. It makes sense to showcase their previous exclusives ahead of the next gen and its exclusives. Plus they aren't known for leaving money on the table. Money is money, regardless of where it comes from.
That is why they are now worth three trillion on the way to 4 trillion.
