I downloaded the .iso for the Windows 8 RP, put it on a bootable flashdrive with Rufus (thanks to Rick P.) and I am posting from the new Windows 8 RP!!
I only have one 500GB HHD so I loaded up Parted Magic, re-partitioned my hard drive so I have three partitions (Windows 7, Windows 8, and System Reserved) and Windows 8 installed perfect! Both operating systems still boot up fine!
