See this from a marketing perspective. You got a sequel to a "mediocre/okay title" to promote, how do you get customer's attention in the flood of other console games? If we release a trailer, how many people will even watch it? Now I don't know the exact chain of thoughts by the THQ folks, but they found something to create buzz:
1.) pornstar promoting a videogame (why does noone think of the kids???)
2.) "special producer" title (does she work on the game??)
3.) connection to jade raymond (parody)
So people watch it and see beside the occasional clevage shot the gameplay footage and go "hey you can throw a dude in a jet engine in this game, i wanna do that" CA-CHING!
So this whole thing might not be that silly in retrospective, from a publisher's stand point mind you, because as a developer I think the game should speak for itself and gain your attention, not someone with big jugs.
The best idea for what he means I have is placing stuff like sparks and fire in the map, but I can't imagine that's something that wouldn't just fall to the mapper to place in as entities once the effects artist creates them along with the geometry and gameplay scripting. They're basically animated decoration when you get right down to it.
