So Tenchu 4 isn’t a Wii exclusive. Just like a member of the Tenchu 4 staff told us and I almost wrote off as a miscommunication, Tenchu 4 is getting ported to the PSP. From Software will publish it in Japan on February 12. Ubisoft hasn’t said anything about the PSP version since we don’t have Tenchu 4: Art of the Ninja here, but you can bet its coming. If Ubisoft doesn’t take care of it some other publisher will.
I wonder how Acquire will adapt the controls for the PSP port. When I played Tenchu 4 it utilized motion control for finishing blows and dodge rolls. Some of these motoins can easily be replaced with button presses, but Tenchu 4 will lose its visceral feel. The screenshots from a Famitsu scan suggest the X and O buttons are going to be flexible action buttons.
