That's a Facebook page for The War of Genesis IV: Spiral Genesis. If I'm not mistaken, it's supposed to come out February 29th, 2012 in South Korea (but I don't know about a Japanese release. If the series follows the pattern of the previous games in the series, it won't get a North American release :_(  ). This page has video gameplay (no translation, though) from all the games in the series including Rhapsody of Zephyr and Tempest as well as art by the Kim Hyung-Tae and the artist of the first 2 games (not sure of his name). Check it out if you have an interest in the series or the artist.
