http://www.eurogamer.net/article.php?article_id=71951 is reporting that Koei's two big PS3 titles for 2007 -- http://www.1up.com/do/gameOverview?cId=3148395 and Fatal Inertia -- have slipped from shipping into Spring 2007 to Summer 2007 releases.

Perhaps this has to do with these titles shifting from single to multiplatform?
