Koei's definitely out to impress as they showcase the first trailer for Samurai Warriors 3, straight from the ongoing TGS 2009. The Sengoku era generals are back for the Wii, and they continue to bring the badass in action.
End of trailer (entirely in Japanese, by the way) shows its release window to be for 2010. No idea when exactly, though. Samurai Warriors 3 is developed by Omega Force
