[“The white waves, the red clouds.” is what the bottom says]
SEGA has filed this trademark for both Europe and US. The US version didn’t have an image, this one came from Europe. See, it’s French on the bottom.
Description from US trademark: “video game software; computer game programs; computer game software; video game discs and cartridges; game programs for mobile telephones etc.”
We could possibly be seeing this on consoles and not just some obscure arcade game. It could also be a name change for the western release of Chaos Code. Though that game doesn’t seem very “Samurai” oriented.
[updated] This is going to be the western release for this iPhone, iPod Touch and iPad game.
