What should Sony do for the next Playstation?

[curl-6]

For the last 30 years, Sony has followed a proven formula of iterative PS consoles, keeping the same core concept but increasing power and capability.

However, given the current technical and economic circumstances, with the cost of both hardware and game development ballooning and graphical progress slowing, do you think they should continue this same blueprint for PS6?

Or, do you think they need to change their strategy and do something different for the next PS system?

If you were in charge, what would be your strategy, in terms of hardware design, cost, release timing, etc, and why?
