They have been.
I know you're going to ask me about the initial pricing and the loss of marketshare, but if you re-read my post you'll understand that they had to break a few eggs, yaknow?
Sony's main goal is to involve itself in as many markets as possible, like MS does. They're taking over the home movie market, will soon be cutting in the desktop computer market, helped cut a slice of out the computer hardware market, and with lower costs+price for the ps3, they will start making a lot more money from the VG market. BR was a big risk for the PS3, and in combination with the wii, MS should have really taken advantage of the opportunity and destroyed the ps brand.
A lot of people tend to forget how well Sony is run, only focusing on their failures and forgetting that Sony really does have their hand in everything, and is one of the most recognizable brand name with some of the most desirable products.
For example, people talk about Beta and mini-disc and how they failed to win the market, while maintaining that they are bad for consumers. What they don't focus on, is their many victories, and the millions of super-satisfied customers who enjoyed both their "failed" products as well as their historic ones. People forget that, overall, MD was profitable, that Beta was profitable, that Sony-Ericcson is profitable. PS3 will eventually break even or be profitable too, and literally sealed the victory for BR.
