It doesn't though, as standard discussion requires, proof of burden is required by the person making the claim.That goes both ways, ofcoure. Theres zero evidence that Sony wont be putting more Sony games on (be it PS5, PS4 or PS6 if that ever comes)
If you claim that god exists, you present proof. Your argument can't be, well prove to me that god does not exist as you're now putting the burden of proof on someone else.
It's like an anti-vaxxer asking someone who is vaccinated to prove to them that they won't die from their recently injected vaccine sometime in the next 10 years. It's not their job to.
In the same way, if you want to prove that PS5 games will be releasing sooner than later, present proof, as the burden of proof is on the person making the claim. Those who oppose your claim are not required to prove the opposite. They are only required to disprove your claim that it will happen.
If you think of it like chess, you can win, lose, draw or forfeit. There will come a time in which a player will suggest to draw. If the opponent rejects the draw and goes for the win, the match must be played out. The opposing player cannot ask a player to forfeit obviously. So the requirement is on the opposing player to showcase how pointless it is to continue and to forfeit without playing out the remaining match. If it's unclear who the winner is then the match is played to checkmate, which is really code for, if it's not clear who the winner is, then you have to let time decide.
Some players don't know when it's time to forfeit or retire. But I don't see that happening here, the arguments are not specific or strong enough which leads to goal post moving. I think everyone here understands the general trend here with Sony and there is no debate about it that it could get there given a long enough time span.
They are only pushing back on how soon, and if that question is being asked, it should be answered, because they are asking for specifics.
