Civilization V Announced

I really only got into Civ IV recently, so the announcement of a fall 2010 release of Civilization V is a most timely event to keep the fever going. Screenshots from Kotaku show an intensely detailed world rendered by a new graphics engine that promises to deliver a great-looking experience. But gameplay has always been the thing for Civilization. Given that Firaxis was bought up a couple years back, there might be questions about how much control they would have over their venerable franchise. I suppose we will have to wait, and hope.
