A demo of SimCity Societies has been released:

Featuring an all-new, revolutionary feature set, SimCity Societies allows you to create your own kinds of cities and shape their cultures and environments. Make your cities green or polluted, contemporary or futuristic, rural or urban. Create an artistic society or a police state, an industrial city or a spiritual community—or any society you want!

While it's not Spore, the latest offspring from Will Wright's classic series might keep you occupied for a little longer while you wait. Check out our game page for some screenshots, or jump straight to the demo download (~830MB).

Didn't this come out about a year ago?

that looks kind of cool. i used to love simtower, no matter how simplistic it was.

oh snap simtower, haven't thought about that game in a good decade
i was an original sim city fanboy myself, would spend hours upon hours perfecting my city only for aliens to come in and attack ;(
