Before you guys get in a huff and get all bent out of shape over "omg why is Intel doing this?" remember. Z87 is Intel's IP. This isn't like the company man coming in to disable your tv because it works too well, this is like the cable company coming to your house because you found a way to get premium channels without paying for it. Yeah, it sucks that some people got something for free that they're getting rid of, but it shouldn't have been there in the first place, and since they own both the chipset and the cpu, I'm pretty sure they are in the right for making sure that you use their intended chipset with the appropriate cpu to achieve the intended results
