The production facility costs were too high to sustain. Sony needed the consolidated capacity once it shifted the ps3 to 299. Sony would have run the PS2 forever had it not been in financial troubles.Thank you for the graphs Zhuge!
If Sony had dropped the price of the PS2 down to $49.99, I really do think they would have had another 100 million units to sell. Making PS2 the market leader for two separate generations.
Alas. We didn't get that level of crazy.
