Basically they relied too much on brand recognition and blu-ray push, thinking that those two factors alone would be enough to encourage their previous fan base to jump directly from PS2 to PS3.
As history showed time and time again, no console maker can get away with that. It happened to Nintendo and now it has happened to Sony. If they learn from their mistakes, then it's all good for them, but if they insist on the same business deal on the next generation of consoles, then the same fate will await them, with the added agravation that their fan base has dimished from the PS2 to the PS3.
Not saying that the PS3 isn't a quality console, currently is my most liked console in this generation, even though I started out with a Wii, and my current PS3 isn't even mine, it's my dad's (i'm on the market to buy a Slim exclusively for me), it has the most quantity of games that I want to play.
But it's competitors have shown that this generation, quality can be found in all three consoles, thus creating a more fair and tighter competition, which us gamers can only benefit from
