The english subtitled second episode of Digimon Xros Wars is out at OnlineDigimon. I hurried with the translation as much as possible, but with editing and encoding and all the stuff it ended up being released just today. There’s torrent and direct download available as well as a discussion thread at OnlineDigimon.
The title of the episode is “Shoutmon, roar!” (シャウトモン、吠える). It’s really worth checking out, as “ep 02” ended up quite dramatic for a second episode. Watch it and you’ll know!
