Known in Japan as Last Window: Late Night Promise and Zangeki Reginleiv, the two titles are due out in Japan in January and February respectively.
Nintendo announced that Zangeki Reginleiv for Wii and Last Window: Late Night Promise for DS are coming to Japan in early 2010.
Zangeki Reginleiv, formerly known as Dynamic Slash (or Dynamic Zan), is an action game from Sandlot, who are responsible for Earth Defense Force. There are over 300 weapons to use and four-player co-op. It's set for a February 11 release.
Last Window: Late Night Promise is the official sequel to the earlier DS title Wish Room: Tenshi no Kioku, which was known as Hotel Dusk in North America. Developed by Cing and set in 80s-era Los Angeles one year after the events of the original, Last Window is another interactive story like the first game. Last Window: Late Night Promise is due out on January 14.
Neither game has been confirmed for a North American or European release.
