will game developers use the blu-ray in the next consoles?

[dmcfan619]

playstation used: cd

playstation 2 used: dvd

playstation 3 and xbox 360 uses: dvd and blu-ray disk

 

i know games dont need that much data like blu-ray or hd dvd but since the blu-ray won the format war against hd dvd wouldn't the next consoles all use blu-ray?
