With Sony going 2 billion in the red with PS3. Yea it will correct itself with PS4.
A company going under or dropping out of a market is also a form of correction. SEGA going third party was a correction, for one (and it's now a profitable company).
Not that I think this will happen with SONY, from all those early rumors it looks like Kaz has got his shit together and the PS4 will be a sane, profitable product.
