IF this is true, that would be great if you want to dual-boot with the upcoming Ubuntu 9.10 "Karmic Koala" whre GRUB2 is standard. Quoting from a wiki:
dear @Jess, cool interface -- I'm waiting this like the Christmass present when I was a child don't tease us anymore
Of course it uses grub4dos, the right sequence for WoW should look like this: MBR -> Partition bootcode -> grldr -> floppy (or other bootable media) image file bootsector's bootcode -> DOS' kernel (any DOS, btw) -> WoW.exe + grub.exe -> bootmgr -> winload
