There are several Best Buy Stores where Returnal has sold out.
Maybe Best Buy didn't order that many.
But it's possible Sony underestimated. Returnal is not exactly right in their wheelhouse.
On to Bluepoint I'm not sure whether the Souls remake while continuing to further showcase their technical capability, pushes their portfolio forward in terms of showing they having the DNA to deliver a strong original product and that seems to be what Sony values , but they certainly tick all the other boxes and even if bought as remake specialists i'm sure like Bend with Days Gone and others they would be given a chance.
I'm sure Sony knows exactly what to expect from Bluepoint, so I doubt a purchase necessitates they be able to make an original product. I think what's important is whether there is perceivable value to remaking these older titles.
Of course, the next step for BP is going to be remaking a title while making more core changes to the formula, such as a Syphon Filter that plays closer to something like TLoU.
If there is perceived value in remaking older titles, then I feel that would be good enough for Sony/ BP. But they're still looking for that high seller, so it's difficult to say whether Sony would make a move, or whether BP are interested.
