From what I've read the support studio had taken the lead of the Last of Us remake. And then Sony put Naughty Dog in charge which started a brain drain of talent from Visual Arts Service Group. They in turn asked to be removed from the project which Sony obliged. And didn't we get a remaster of sorts of Last of Us for the PS4 Pro debut? At least that's how I remember it and while a great game I'd rather Naughty Dog bring us something new.
As far as Sony Bend is concerned. I'm bummed they will not be able to continue the story in Days Gone. It ends on a cliffhanger and now we won't get any closure. But, Sony did put them on another project so that's good. I think they have a lot of talent and it showed in their approach to the crowded zombie genre.
This whole thing seems to me to be a nonstory. Or, rather seems to be another example of J. Schreier injecting his agenda. I used to like his reporting, when it felt like reporting. Now his stories feel more like screwing the facts to support his agenda.
