It's funny how people think investors are stupid. They're quite smart, actually.
They know Sony can't sell the PS4 at a profitable price while also obtaining reasonable market share in the 8th generation. It's either they sell it at a profitable price and get crappy market share, or they sell it at a loss and get higher market share (and who knows if it will even be good market share, even taking a loss. Look at Vita).
Sony might be forced to actually remove features to bring the price of PS4 down. Then people wll be more pissed than ever. They're in a very bad spot, to be quite honest.
This exact situation is probably what Nintendo was banking on the entire time with Wii U. I'm sure they didn't believe the market was ready for a true 8th gen console yet without throwing away money to sell the damn thing.
