A guildie of mine showed me this link and I have to say, I was shocked. I raid 25 man and, while I knew that many in the WoW community had made the switch to 10, I had no idea the change was this severe. I wonder what this means for the future of raiding. If these numbers really are accurate, I wouldn't be surprised at all to see Blizz pull 25s entirely. I think that would be a sad day though...
