Some of the shots look offline (pre-rendered), but not in the fashion of being unplayable. I get the distinct vibe, we're looking at a mixture of polygon models (vehicles, characters, items, vegetation/trees, etc...) with controlled (camera movement) static offline scenery. Somewhat reminiscent of the earlier Resident Evil games, especially Resident Evil Zero. But better... miles better. I could be wrong, but the actual scenery looks static, with aliasing only occurring around poly-meshed based objects.
I'm not nocking this, I actually would love to see more games using high quality pre-rendered backgrounds/setups... freeing up the GPU for better character geometry, great lighting and shadowing, etc. But yes, I know, static backdrops/environments can be limiting to camera movement and gameplay mechanics. I think I'm just an old softy for Resident Evil Zero...
