Lets see... Extrenal Blu-ray add on will enable you to play your movies only. If you need to play games as well, they will need to do more coding into it.
MS is not stupid and they are not going to write 2 codes engine for blu-ray and dvd which in the end it is more costly. With blu-ray, you can even do more thing with it.
Well you can use it for watching DVD. If they do adopt games for blu-ray. I dont think it will be quite useful.
My meaning of throw means disposal. if you know how to dispose it. The coding is not that simple. They have to redo from the beginning.
hardware? Ps3 hardware is better then Xbox 360. did you see the specs? I saying throw current xbox 360 if they do adopt blu-ray games in 360.

You sure about that? You might want to reconsider your statement after doing a better research.
Ya. But the game was more concentrated on Xbox 360 then PS3 that why it looks more better. I think the pro street was the other way round.

The problem why Xbox 360 game turn out to be better then PS3 because of the coding. i remember there was a game where it suppose to be PS3 exclusive but in the end went into Xbox 360 due to the coding difficulty in blu-ray.

Anyway this is already out off topic.
