PS3 won't pick up casual en masse because it was designed to fight off the 360. Better graphics, comparible online, similar games - high price.
This left a huge openning for Nintendo to come in and steal all of Sony's casual audience which they smartly realized and capitalized on with the Wii.
The Wii appearing at the Academy Awards is proof of it's mainsteam appeal. PS3 will never have that.
Blu-ray will be increasingly important, and will likely push PS3 over 360 before the end of the generation. But PS3 offers too little to the casual market to capture many sales. People will just buy a blu-ray player, or an upconverting dvd player, or worse, buy a PS3 but hardly ever buy games for it causing it to have a low attach rate.
