Well other than it being too big of an architectural change, no one really likes to work with Nvidia. Whether it be Apple or Sony or many other list of companies, a lot of them got burnt in the past by going with Nvidia. And Nvidia as a company isn't in the same desperate position to get design wins as Intel is so even if they went to Nvidia, Intel would undercut them severely. Unlike RDNA, Arc as an architecture can actually go toe to toe in feature set against Nvidia but the problem in the PC space is driver support.
I do agree that it's very early to call it but honestly, this is their third attempt and I think the strengths and weaknesses for RDNA is clear. But yes, a lot can change by the time ps6 comes out.
