Is the next version of windows called Windows 9" ?

Worried that Microsoft was going to keep the
“Threshold” codename on the next version of Windows?
Fret not, it probably won’t. In a speech to employees,
Alain Crozier, president of Microsoft France, called the
new operating system “Windows 9″ quite recently, and
there is tape of it .
Microsoft has followed up with a statement for the
ages: “On September 30, we will be providing an update
on what’s next for Windows and the enterprise.” The
comment provided to French media was more extensive,
adding something to the effect of “there is no name
yet!” (Spoiler: there is a name.)
So Microsoft says “Windows 9″ out loud, and then says
that its employee — a bigwig, to boot — was mostly
talking out of his ass. Microsoft is hedging here, and
that’s to be expected.
What’s the chance that it is called something else?
