I missed that part on the other response.
That actually still remains to be seen. Obviously they are making moves towards that but thus far they don't have a solution for playing ps3 games natively, ps2 games are being handled very badly, and psone is non existent.
Even for ps4 games they don't seem prepared to moving the platform beyond the console, and the neo development seems to be: You code and optimize for both as they are largely the same but on neo everything runs faster.
Given that even nintendo is moving to a device agnostic platform I suspect sony will too, but as of now nothing has been leaked or announced in that direction.
