Ender's Game Game?

I was just scanning through PSP releases on Metacritic, and saw Ender's Game: Battle Room, (title pending) with no release date. The developer was listed as Chair Entertainment (the folks who did Shadow Complex for XBox Live Arcade). I hope they pull it off. The battle room scenes in Ender's Game seem an ideal spine on which to build a game. I didn't check to see if there are versions for other platforms.

In other news, I'll be signing a contract this week for a couple books. I prefer not to share details until everyone has signed off, but I think my readers will be pleased.
