As is expected from ArenaNet, the trailer is beautiful. Starting with concept art, we actually get to see game footage in a rather long montage of landscapes. And jumping! There is a bunch of that going on, watch for characters running around, exploring this new dimension to their modes of movement.

There is also an FAQ for the game available.

Update: Something is wonky with the server, and it isn't server the video. You can download it directly (gw2-trailer.ogv), or you can check out the video trailer page.

Watch the teaser trailer, funny stuff.

The first Battlefield Heroes trailer is out, half promotional material, half gameplay. I'm kinda digging the visual style, but the gameplay footage isn't grabbing me. It's free though, so it'll be easy enough to play test ^_^
