Reasonable on 22 February 2010
It could easily be real, just using the engine for rendering well above what you're going to get in motion in an actual game. Most good, similar engines can produce images and short, controlled scenes way above what you'll get in the game.
That's why so often everyone get's so excited at some engine generated cinematic then finds the actual game lesser visually.
Try to be reasonable... its easier than you think...
