interview with GamePro, Heide said, "It is not a luxury to have Blu-ray, but rather a necessity, as compression only gets you so far."
He added that the one level shown at E3 took 2GB of space (approx. 24% of a dual-layer DVD), which is unsurprising since he said the same thing during an E3 presentation. Assuming he meant assets exclusive to the level (we're guessing quite a few vehicles and enemies will be seen in multiple levels), that'd make for a rather short game on DVD. Still, it's hard to be convinced by the statement when reusable assets are factored in. The real decider will be the final product; we're hoping Heide's statements indicates a plethora of content when Killzone 2 comes out.
Heide also lauds the Cell processor. We wouldn't expect a Sony developer to join in on the hardware hate-fest, but we're not hearing a lot of other developers at this point standing up for the PS3. Killzone 2 still does not have a release date.
