Ok I resurrected this horse.
I want to know what you think the Revolution's big secret is? You know the last big Revolution feature Nintendo has yet to reveal.
Now what I want here is a community brainstorm. As such there is no right or wrong. So please do not criticize or comment on other people's ideas in this thread. God knows there's plenty of threads for that. And that goes for me too. Believe me I'll have a hard time.

But I shall adhere.
What I will do is edit this first post every so often and update it with every idea posted in this thread. Anyway please no debating or commenting in this thread about the validity of ideas. Just present a guess and a short description of it and what benefit it will bring the Revolution.
