Ignition has just revealed a new project via a launch website called El Shaddai New Project 2012, which also includes some text which can be translated to "Who is the ultimate angel who God speaks of?"
It is still unclear what this teaser actually is, as Andriasang points out that the El Shaddai franchise branches out of the video game industry and also includes jeans. However, it could well be a sequel to last year's El Shaddai: Ascension of the Metatron.
If this is the case, it would be an interesting one as in the West, El Shaddai didn't sell anywhere near as Ignition must have hoped. It could be a game that says as a release in Japan, if it is indeed a game.
Gaming Union reviewed the first video game in the franchise, El Shaddai: Ascension of the Metatron which came out last year. The review can be found here.
