Microsoft blog suggests they may rename metro 'Windows 8 Modern UI'

Just came across this blog post:

It mentions "Windows 8 Modern UI." I know new info that metro is going to be replaced with "Windows 8 Applications" just surfaced today, but seeing as there has been no official new name from Microsoft is it possible that metro is now going to be called "Windows 8 Modern UI"?

Or is that something totally different?
