@ moondeep
you stated this:
"However, the future success of Sony's Bluray hinged on the PS3 being dominant in this generation like the PS2 was in the last generation."
your statement is "implying" Blu-Ray is just a Sony format and that IN ORDER FOR Blu-Ray to make it it needed the PS3.
your Opinion is noted but i disagree.
1) Sony is not the only of company that make's Blu-Ray and has never been the only company to do so since Blu-Ray first went to the market in 2003 there was more than just Sony creating Blu-ray recorder's, and optical drives.
2) 11 of the largest optical drive manuf. all have been on board with Blu-Ray since 2002 and while the Whole HD DVD vs' Blu-Ray was going on they still supported Blu-Ray.
The PS3 was just another device that had Blu-Ray ,The Blu-ray format would have made it even without the PS3 ..Yes it would have taken longer but it still would have made it. was it a good choice for Sony to put Blu-ray into the PS3 some say yes some say no it was not.
Its all Opinion, but for what ever side you choose Sony did what they did because they felt they needed too. Sony feel's Investing into Blu-Ray was a wise choice and Sony has been investing since 1997..along with 11 of the largest Optical drive manuf. all felt the same Investment into Blu-ray was a good choice.
