The White Knight Chronicles English trailer has been released by the developers. After seeing this, I can't wait until it comes out! =D This will probably be one of the only must buys on day one for me.
Here's the trailer:
Level-5 has a reputation of creating awesome RPGs like Dark Cloud and Rogue Galaxy, so WKC has a lot to live up for. I've heard about voice chat and online co-op, so it should be something worth looking out for.
