The many versions of Windows 8

Are there more versions this time?

The complete lit [sic] of SKU available in Windows 8 according to the registry file is-

• Windows 8 Enterprise Edition
• Windows 8 Enterprise Eval edition
• Windows 8 Home Basic Edition
• Windows 8 Home Premium edition
• Windows 8 ARM edition
• Windows 8 Professional edition
• Windows 8 Professional Plus edition
• Windows 8 Starter edition
• Windows 8 Ultimate edition

I’m not sure why Microsoft thinks this is a good idea.
