Andriasang translated the relevant blurb: "New Games: Will release games that combine Tecmo and Koei titles. The aim is to reach fans of both." The identity (or number) of games, and the identity of the titles that Tecmo and Koei plan to merge are unknown, which means we can amuse ourselves briefly by coming up with our own, like Dead or Alive: Xtreme Romance of the Three Kingdoms, Rygar's Ambition, Dynasty Monster Ranchers, Gitaroo-Man Gaiden Sigma, and Mighty Bomb Genghis Khan.
We've checked in with the North American branches of both Koei and Tecmo in an effort to find any additional details about the plan.
[Update: Tecmo declined to comment, indicating that the US office didn't know any more than we did about this.]
