Quite honestly, all depends on what Microsoft ends up doing. For example, if they stop putting their games on Game Pass day one and have that service be what it was pre-Sea of Thieves, then they literally have nothing at all for me to stay on the platform whatsoever. I will simply stay with PlayStation 5 as my new primary gaming console which only Microsoft could fuck up my entire generation, force me to switch primary gaming consoles and give me my first personal loss as every primary gaming console has always been the best for me (Super Nintendo/PlayStation/PlayStation 2/Xbox 360/PlayStation 4) and this will be the first time that I not only switch primary gaming consoles in the middle of the generation but also lead to my secondary gaming console being ranked higher than the console that started the generation as my primary gaming console.
With the PlayStation 5 Pro releasing later this year, im expecting it to be superior to the Xbox Series X specification wise so I will make the switch when this happens. If Microsoft's first party games are still on Game Pass day one, I will keep the Xbox Series X and play their games the same way I do now via an $11 monthly rental. But all third party games will then be played on PlayStation 5 starting with the Pro. If there's no more day one games on Game Pass, I will then trade in the Xbox Series X along with the PlayStation 5 when I pick up the PlayStation 5 Pro and I will simply be what I haven't been since the NES as a kid/teenager - a single console owner.
In all honesty, im actually hoping Microsoft eliminates the Xbox brand and consoles. Or at the very least just says that the Series X/S are their last consoles. Either way is fine by me.
I also hope that while it probably won't happen since the vast majority of consumers wouldn't care either way, I hope that their games don't sell whatsoever on PlayStation AND Nintendo. Hope it all dies and gets washed away.
