Why has there only been one 3DS FPS game announced..?

[snowdog]

The only 3DS FPS game I've heard anything about is Conduit 3D...I was expecting at least one to be available if not on launch day then at least one soon after launch. A 3D FPS game on the go would fly off shelves, particularly if it was the only one available. What are these publishers thinking..?!!? :o/
