Yes, I posted all the facts in the posts on Steve Huff (see link provided). Scroll to the bottom of the posts, my name there is Sergio.
D800 + 28mm + 85mm = 1675g
M240 + 28mm f/2 + 90mm f/2 = 1457g BUT, I think a handgrip is essential with the M, so that puts it over the weight of the D800 kit. Even without, you're talking about a half-pound difference... hardly cause of stating that the D800 is 'massively' heavy and a 'pain in the butt' to carry, as many reviewers claim, when it's compared to the Leica M.
