I have been seeing in lieu of Sony's ongoing profiting issues, that people say that the playstation divsion could simply spin off into its own thing or be bought out. I get the impression that a lot of people are okay with this scenario, but i see some issues with that.
One being that there will be a lot more studio closures and/or layoffs. This would great constrict all of the new ips they make.
Second point is about Playstations ability to have a wide berth of distribution and advertising without the resources and connections that Sony has.
Lastly, all of the potential companies who would be able to financially secure the playstation division, are far more interest in the mobile market or their own micro console.
I liken this response to the "they should become third party" argument that we hear about Nintendo
