Today, Nintendo announced a delay for Steel Diver, their Nintendo 3DS submarine simulator, and Konami did the same for the Nintendo DS PowerPros golf game Powerful Golf. Both titles were scheduled for release this Thursday and have "TBD" (to be determined) release dates.
While most delay announcements are for recent titles, Kadokawa Games pushed back two PSP games further in their schedule. The Mahjong of Suzumiya Haruhi-chan was originally slated for March 31 and it is now "TBD" according to retailer HMV. The game is exactly what it sounds like, a mahjong game with Haruhi characters.
A Certain Scientific Railgun, a PSP game based on the anime series of the same name, was moved from May 26 to TBD. We haven’t heard much about the video game adaptation since its announcement, but the title is said to be an "adventure" game, which probably means its going to be visual novel-esque.
