Is Sony even financially ready to market a PS4? Their credit rating is now classified as junk status. Their various other divisions are bleeding money (TV especially), and the company as a whole is in deep debt. They made a little profit on the PS3, but the development (and subsequent poor sales) of the Vita sunk them back in.
As we all know, Microsoft lost billions on the Xbox, but their Windows and Office divisions make up that lost profit. Sony doesn't have that luxury right now.
I know about all the rumors about PS4 devkits and hardware specs, but Sony can't take any more chances with making cutting-edge hardware. They just can't afford the potential losses if the console fails like the Vita.
Is Sony really in trouble, or is all of this talk overblown?
