Naughty Dog 100% Sure Uncharted 2 Impossible on Xbox 360

"I guarantee that this game couldn't be working on Xbox 360. It would be impossible. I'm 100 percent sure of this." That's what Christophe Balestra, co-president of Naughty Dog, has to say about Uncharted 2 which is apparently just over a week away from submission.

One of the reasons for that, apparently, is the game is maxing out the space offered by a Blu-ray disc. "First of all, we fill the Blu-ray 100 percent, we have no room left on this one. We have 25GB of data; we're using every single bit of it", he told Ars Technica. (Note: MGS4 comes on a dual layer disc, which ups the amount of storable data to 50GB.)

Going on, Balestra explains, "It's the combination of Blu-ray and hard drive. You can play the entire game without loading. We don't require an install. We're doing all the post-processing effects on the SPUs [Synergistic Processing Units]. The quality of the depth of field we have, you can't do that on the Xbox."

Evan Wells, another Naughty Dog co-president, said back in the distant past that the first Uncharted only used one third of the PS3's processing power.

Anyway, further on the interview gets really techy. If you're in that sort of mood, catch it here.
