What do you wan't to see in a demo?

If Chris Sawyer and his crew decided to release a demo, what new features would you want to see in it?

I would like to see Premier launchers, Intamin inverted and hyper track, all the new track features (banked drops, smoother crests, etc...), the ATM machine...lol, and at least 5 other things that they haven't shown us YET.

The reason I didn't put the Scenario Editor is because I want to have something big to expect in the full release. I would like to give it a try, but they need to save at least several big things to have us anticipating for.
