The 200 is a big, bulky camera and for weddings you'll want a Firestore which adds considerable bulk and weight. I'm not a huge fan, and even though as an EDITOR I don't like what Sony has done with the EX1 in terms of how it plays with FCP (sort of well) and Avid (not at all), the images that camera captures are stunning.
This camera has its caveats of course but the picture quality is stunning for the price. Plus you can swap SXS cards (Sony's P2 format) on the fly. It's off balance making hand held shooting a challenge (use two hands) and the menu system will take work.
But overall a perfect choice for a wedding.
