Nice trailer, looks like the style was slightly influenced by Teddybear Crisis. There are a few similar angle shots (tree above jump panning up) and The Go! Team song in trailer. Not saying L1 is biting since it's all good stuff.
Aweesome editing, very tight.
When it says HD does that mean
1) Shot on HD digital cameras?
2) Shot on film and telecine at HD res?
2) Released on HD-DVD / BluRay?
