After looking at the P4R533, it really does seem that Iwill is starting to focus on the high-end/server market rather the home-desktop market. The performance of the board is amazing and so is it's stability- definitely two features that will appeal to the high-end market. On the other other hand, overclocking and onboard features weren't exactly the best we've seen- also something that the high-end market is not that interested in. If you're not the overclocking/tweaking type, then the P4R533 will be a good choice.
