Grasshopper Manufacture announced that their shump Sine Mora, will be available on XBLA starting March 21st.

That's not the end of the story, though. Grasshopper actually had a contest on Facebook where they asked fans to guess the game's release date. Ten people hit the nail on the head, so they used a ridiculously complicated method to pick a single winner, which they recorded for all to see.

I'd explain what happens in more detail, but then you wouldn't have any reason to watch that video up there, would you?
