I will bet that at least 1/4 of the people who bought the PS3 have only used it for Blu-Ray.
I'm pretty sure Blu-Ray is going to sell 15-20 million PS3s, and Blu-Ray total will sell 125 million players by the end of 2018.
Blu-Ray isn't the driving force though, it is the extra nudge that will make people shell out money for it.
Kimi wa ne tashika ni ano toki watashi no soba ni ita
Itsudatte itsudatte itsudatte
Sugu yoko de waratteita
Nakushitemo torimodosu kimi wo
I will never leave you
