That trailer wasn't even handled by GG or anyone at Sony, so it has not in anyway shape or form effected the release of the game.
The CG trailer by Axis has clearly been used extensively as a look development reference, and not just the modeling/lighting/action coreography part; but also as a guide for the graphics coders about which rendering technologies to concentrate on. GG designers were heavily involved with the movie as well, in storyboarding, direction, pacing etc.
