One big unknown, however, is what the next version of Windows will be called.
Windows TH/Threshold was likely just an internal codename and wouldn't make sense as a marketable name for the Windows refresh. During the months leading up to Tuesday, many expected Microsoft to name its latest release Windows 9 in keeping with the Windows 7 and Windows 8 releases. The name "Windows One" has also been bandied about.
An interesting theory that gained some momentum in recent weeks, however, is the notion that Microsoft may dump the numbering scheme and simply call everything Windows.
That appears to be what Microsoft is doing on mobile, largely dumping the "Phone" in Windows Phone and just referring to its mobile OS as Windows.
Doing something similar on desktops and tablets could help emphasize Microsoft's focus on creating a unified experience across its software for PCs, tablets, and smartphones.
Two other questions still outstanding is when Microsoft plans on releasing a public preview of Windows (9) and how much it will cost to upgrade to the new Windows when it hits store shelves.
At the moment, most Microsoft watchers aren't expecting Microsoft to release a public preview until early October, which means we could see a beta version of the new version of Windows as early as Friday, or the following week.
As for pricing, the president of Microsoft Indonesia recently said Windows (9) would be a free upgrade for Windows 8 and 8.1 users.
While actual details about pricing and upgrade plans may not surface anytime soon, we should find out on Tuesday when the world will be able to get its hands on the public preview of the next version of Windows.
