It's not a habit for their new games, and I'm not complaining at all since here is the first Webisode of Lost Planet: Extreme Condition. The game will be released at the end of December in Japan, and a few weeks later everywhere else.
It's worth noting that the video has been encoded with the VC1/WMV9 Advanced Profile codec, as will be more videos in the future here. They work natively with the 360, but require to install either Windows Media Player 11 or at least the codec itself you'll find on the video download page. Mac and other alternative OS users will have to use a nightly build of VLC, mplayer or any other ffmpeg based media player.
