Download Windows 8 On Mac OSX

When I go to Windows 8 download shop and initiate a download, I get an exe file which I can't run on OSX. I've been browsing through their website trying to find an appropriate location where I can get access to the ISO or a special installer for Mac OSX (wish to run it using BootCamp) but without any success so far.

Does anyone here know how to download Windows 8 on Mac OSX? I'd really appreciate your feedback on the same.
