Yeah, I watched it earlier. Prerendered, but the actual Motorstorm (while not exactly like the trailer) looked very close and still remarkable. If the jungle foliage is anything like Uncharted, it will look very nice. Besides, MS is definitely not the only game to release prerendered stuff as a trailer. But they are one of the few to make the final product look close.
Speaking of which, I'm amazed at the graphics that they are pumping out of the DS these days. http://media.ds.ign.com/media/905/905252/vids_1.html
