Is this a troll post? Or...? Like are we just having some fun or do people seriously believe the whole “Sony third party for Nintebdo” thing?
Yes, it is a troll post. People are feigning that they do not know thay Sony Computer Entertainment and Sony Music Entertainment are 2 different entities. They're also ignoring that Sony Online Entertainment used to exist until recently and was making PC games.
Edit: By the looks of it, it seems that some people are taking this seriously.
