I'd imagine most people picking up Civilization V will know exactly what they're getting themselves into, but just in case you don't, you can always check out the demo that will be released in September ahead of the game's release.

Actually, I'd imagine many people picking the game up regardless will be interested in seeing how the game's new hex-based map system - the single largest change to the series in its long history - works out.

No further info like a release date or how long it'll be was released, only a promise that those details are "coming soon".
