You're the one who keeps turning this into an argument, not me.
I don't know why you have such a bug up your ass about it.
You seem to think once XSeed starts publishing on PS4, they are legally forbidden from publishing on any past platforms.
Let's look at a different example.
Atlus put out Catherine in 2011.
Then they put out Devil Survivor 2 on the DS, even though the 3DS was already out.
They still published on past platforms.
What is so difficult to grasp about this?
