GameSpy has posted a preview of the seventh and final expansion pack for The Sims 1: Makin' Magic. It's not much more than an overview of the possibilites of the expansion though, and they probably weren't able to play it themselves at Camp EA. There isn't much in it that we don't know yet:

"Putting magic into the world of The Sims seems like an odd choice, but the developers are clearly aiming for the lighthearted sitcom approach of Bewitched or I Dream of Jeannie, rather than the sinister direction of The Omen or The Exorcist -- so don't expect demonic little children or even kids who can projectile vomit pea soup. However, you can take your established sims, head over to a new carnival-themed destination, and take a trip to Magic Town where you'll get to perform mind-boggling tricks and unlock powerful spells."

It's a nice preview, but it doesn't add anything great. You can find it right here. Enjoy it.
