I do believe that BluRay Disc's current 'success' is due in large part to the PS3. Heck, I myself have bought 3 BluRay movies just because I saw them (Casino Royale, House of Flying Daggers, The Queen). The PS3 is definitely a huge factor in Sony's strategy to 'win' the HD format war.

While I don't agree with Sony forcing it down us gamers' throats right now, I do see the benefits with the storage space and whatnot.
