Blu Ray on Nintendo and Microsoft following Sony will expand Blu Ray adoption, but yes Sony has already done most of the work that needed to be done the same way they did with DVD's during the PS2 era. Blu Ray has been big a relatively short amount of time. It wasnt until like half way through the PS3 era that it started to pick up speed on stand-alone players. DVD's first came out in 1995 and no one could afford it until the Playstation 2 in 2001, so the Blu Ray market will slowly eat away at the DVD market.
