Eh. thats the kind of mentality that got MS complacent and back firmly in last place. Brand recognition is fickle among casuals. Exclusives sell consoles. Its been proven time and time again. go look at how many consoles were sold in April 2008 when GTA4 came out. less than 200k each for both.
It's no surprise that Sony continued the momentum from year 4-7 for the PS4 while the xbox one literally crawled to a halt after a strong start as we can see here. Thats when their big hitters starting coming out one after another. Horizon, GT7, GOW, Spiderman, Days Gone, Death Stranding, Ghost of Tsushima and TLOU2 while Xbox after 2016 released two forza games and one gears game, and called it a day. No third party saved them. Not even RDR2 after GTA4 and 5 both sold better on the x360.
In short, they NEED the exclusives just like nintendo and xbox. they need them every year and they need them to be huge. not quirky stuff like hifi, returnal, ratchet, or deathloop.
