Cubase 6.x and Windows 8 support?

I don’t expect that Cubase 6.x (or Cubase 5.x) are officialy supported in Windows 8 yet, but will they work (without too much problems? (Since Windows 8 RTM has been officially released to MSDN/Volume License. Retail will follow on october 26)

There have been posts on this form with users sucessfully running Cubase 6 under the Windows 8 releases.

Here’s a few threads that discuss it:

As a side note:
Does anyone know if it’s possible to turn off the phone in Windows 8?

Thanks!
