It has absolutely nothing to DO with the Mac Mini, but we've already seen kexts with the 9400M in the Mini, so it's obviously coming.
What?
We've seen proof of new models of the iMac and Mac Mini in existing OS software.
at this point you could even use the new white macbook in clamshell mode as a mini replacement. I am sure its specs are very close to what will be in the new mini whenever it is out.
And you could use it without a displayport adapter!
