OS X for Intel?

MacOSRumors posted an interesting blurb hinting at a MacOS X for Intel.

For the loyal users who have been following this for a while - this isn't a new idea. NextStep was originally available for Intel and, in fact, ported ot Mac as one of the original steps. The beauty of NextStep/OSX as a development environment and the potential for Apple was this: write once, deploy everywhere.

This is the significance... get the developers, then you have the apps.
