It's something that has been done unofficially for a while, but GW now have a Golden Demon winners page on their website. Compared to the lag you get caused by publication deadlines then I think these will be much earlier than you'd get to see them if you waited for the booklet in White Dwarf (although the booklet will still be better).
I'll look at them more later, but from my initial two clicks I've noticed a mistake already. The W40K monster thumbnails (as tiny as they are) are the opposite way around to the images when you click on them. Not sure which is the correct Bronze one, but hopefully GW will sort it soon.
