Did Blu-Ray kill Playstation?

What is notable about this report on video game console sales is the fact that the once dominant PlayStation brand is no longer worth a mention.

Other reports state that sales of PlayStation consoles are down 19% year on year, XBox and the mighty Wii are both growing.

It is not hard to see the reason, Sony's decision to use the PlayStation franchise as a launchpad for their Blu-Ray format is going to be seen as one of the biggest and costliest blunders in the history of technology marketing. Even though Blu-Ray has defeated HD-DVD, the cost of the battle is is already greater than the potential patent revenue before the value of the PlayStation franchise is considered.
