The death of the console as we know it will happen in around 2 decades, what does Sony already claim 80% or some shit of its sales are digital? You already don't own anything. Graphics will plateau to near realism and streaming will catch up to be non noticeable in ping time as compression and speed grow.
Sony would much prefer to have 100 million paying subscribers for $25 a month then to be shipping hardware. The profit margin on the consoles would be largely small to who cares when you factor in development and engineering, their main gross profit comes from micro transactions and their own store fees.
We'll have three apps eventually across any platform that has a screen and can sync a controller, Microsoft Nintendo Sony. Even if this doesn't happen in the next two decades it's inevitable.
