The PSP version of From Software and Acquire's Tenchu 4 (Wii, PSP) has finally been dated. Granted, the release date is for Japan only, but it's a date nonetheless.

According to the official Tenchu 4 site, the game's PSP version will launch in Japan on February 12, 2009. For those who are interested in importing the game, price has been set at 4,800 (US 50.40)

No word yet on a U.S. release, but if we're gonna go by how far apart the Japanese and North American releases of the Wii version are, I guess we're looking at around July at the earliest. Hopefully, at least. Keep checking back here for updates.
