We hadn't heard anything about the US localizations of the two Tendo Dokuta games since November. Siliconera is reporting today that the two games, called Lifesigns: Hospital Affairs and Lifesigns: Surgical Unit are being published by Dreamcatcher Interactive and released on May 15 and June 28 respectively. A quick jaunt over to EBGames' webpage confirms this information for Surgical Unit (if EB is to be trusted), but Hospital Affairs is nowhere to be seen.
Tendo Dokuta was a launch title for the DS in Japan. It's amazing that someone's just now getting around to localizing it!
