For me Sony are the big wildcard in the near future now. We know Microsoft is pivoting towards streaming and getting gamepass everywhere, what if Sony does what it did this time around and just doubles down on how we currently play games? It worked brilliantly for them this time when Microsoft was talking about always online and eliminating used games.
I don't know, Phil Spencer has been relatively clear that while they are pursuing streaming they still absolutely intend to offer high-performance consoles for people that want that experience (at least for the near-future, which I take to mean at least the next console cycle). MS is big enough that they can pursue both paths simoultaneously, especially since other parts of MS (see: MS Office cloud services) are putting significant R&D into cloud services. Sony would appear to have the most to lose here.
