Level-5's juggernaut RPG White Knight Chronicles debuted in Japan about 2 weeks ago and garnered an absolutely steallar reception.  The PS3 exclusive RPG sold over 132,000 copies it's first day and went on to sell over 200,000 copies its first week.  Media Crate just revealed their hardware reports for the same week, and PS3 sales are up to 46,000 units sold - a 16% increase from the weak before. 

Though the PS3 still trails the Wii almost 2 to 1, Sony is optimistic, with several 1st and 3rd party blockbusters due out in the region in the next few months, including Yakuza 3, Street Fighter IV, and Resident Evil 5.

Akihiro Hino, CEO of Level-5, has also officially announced, in light of White Knight's success, that the title will definitely be making it's way to the US.  Hino wouldn't budge on an exact release date, though.
