An extended, higher-resolution version of the previously released Twilight Princess trailer has been made available at IGN. The trailer highlights some new things - the flying creature mentioned before isn’t Link, nor is Link riding him, he’s actually holding Wolf Link in his talons. We also see more of Hyrule Castle before Link pushes back the Twilight, and by using Wolf’s “Sense” ability, busy townsmen and rows of Hylian Guards can be seen ‘the way they were.’
This trailer has to be downloaded - it’s a little shoddy (it ends rather abrubptly), but the new features it highlights are really interesting and exciting.
