Lee Carus had a lot to do with both of them.

To me the 2048 trailer looks like the unreleaed WipEout Trinity concept trailer that Lee and his team put together back in early 2007. Maybe the Bladerunner-esque pouring rain & neon city drop is Lee's "director's trademark", like Michael Bay's jangling keys and slow-motion of the ensemble cast walking towards the camera?

I'll ask him about it. Actually, I wonder if they'd ever release that WipEout Trinity concept video - the idea for the game was flawed, I think, but the rendered concept video was fantastic. To my mind it was like if Pixar chose to make a WipEout movie.
