There aren't really any spoilers in the video. The guy just looks over interesting locations but doesn't stop. Takes him 30 minutes!

The best thing about it is how gorgeous everything looks. I've seen some screenshots from PCs on low, medium, high, and ultra. They say the Xbox is equivalent to low to medium PC settings....I say BS. This video looks like the high to ultra PC screenshots I've seen. I can't wait another 10 more hours!!!

EDIT....

New link. Sorry guys: http://www.youtube.com/watch?v=-YZctTgENLY

If that link doesn't work too, just search youtube for "30 minute journey across the map"
