Square Enix believes one Blu-ray disk isn't sufficient enough to store next-generation titles on.
The firm's chief technical officer Yoshihisa Hashimoto discussed the publisher's E3 tech demo for their next-gen engine Luminous. He explained that the power of the processors utilized within the demo paved the way for assets stemming from the CGI video to be carried over to the real-time demo, which he believes is an aspect that may very well be possible for next-gen games.
"That's what we're expecting to do. For the backgrounds used in this - the mountains, the houses - we are using exactly the same assets as are used in the Visual Works CG version."
However, Hashimoto stressed that storage space for visuals of such quality may not fit on Sony's Blu-ray format.
"Of course, it's too massive of a data to use in a game as-is, but I think the look and feel will probably remain. If we had time, we could've compressed the data even smaller. We didn't have time to do that, so we just used the same master data - but it can definitely be reduced."
When asked whether Blu-ray would be sufficient, he admits that there's a possibility one disc just won't be enough.
"Yeah, that could be a challenge. There's a possibility that just one Blu-ray may not be sufficient. We have to really consider the mechanism of compressing the data carefully."
The successors to Microsoft's Xbox 360, which itself has been rumored to have a Blu-ray drive, and Sony's PlayStation 3 are heavily rumored to be launching late next year.
