Hi, It is indeed too early to make a definitive judgement. However there are photographers that had a chance to shoot wedding-like situations with D-800. One of them is Cliff Mautner (who I consider one of the best on the wedding photography arena). He points out some interesting topics on the discussion (like ISO performance comparable with D3). Maybe worth to check his blog: http://www.cmphotography.com/blog.cfm
