I'm tentatively interested.

Are we talking a game set in the real world or a fantasy world? Likewise, are we talking hard science fiction or soft science fiction? Meaning, will the game be based on what's possible in the real world, or are we throwing realism out the window in favor of fantastic steampunk flying fortresses and subterranean colonies?

On top of all that, will this be another World in Revolution-style stats game, or do you have another system in mind?
