For Intel-based PCs, the number of versions on offer has actually been simplified: the now common process of releasing Starter, Home Basic and Home Premium (amongst others) versions shelved in favour of launching just two SKUs - Windows 8, and Windows 8 Pro.
Enterprise will also be offered its own bespoke version featuring software assurance agreements, but it's Microsoft's plans for Windows 8 on ARM devices referred to as Windows on ARM or WoA up until this point that's generating the most chatter.
Do no ARM
Rebranded Windows RT, it's the only version of the three that won't be sold in boxed form, with Microsoft instead pre-installing the OS on all ARM devices, whether tablet or PC.
The extent to which the name will be used at as a consumer level, however, is unclear.
Microsoft had previously suggested Windows 8 would be pushed as a united front, but it now appears Windows RT notably lacking an '8' in its title will be offered as a distinct package.
Desktop differences
This ties in with the fact that users will be unable to install desktop apps on the platform (Microsoft Office pre-installed), with customers instead encouraged to make use of the Metro, touch-friendly apps sold on the Windows Store.
"This single edition will only be available pre-installed on PCs and tablets powered by ARM processors and will help enable new thin and lightweight form factors with impressive battery life," details Microsoft on its Windows blog.
"Windows RT will include touch-optimised desktop versions of the new Microsoft Word, Excel, PowerPoint, and OneNote.
"For new apps, the focus for Windows RT is development on the new Windows runtime, or WinRT, which we unveiled in September and forms the foundation of a new generation of cloud-enabled, touch-enabled, web-connected apps of all kinds."
Windows 8 is expected to launch later this summer.
