The port is real and "official".
However, it is unlikely that any mac version would make it to the first MOS 2.0 batch: Pegasos I, Pegasos II and Efika come first.
This Mac port is not ready either, so hold your horses. Don't go out spend your last savings on Mac Mini assuming you can grab MorphOS for it tomorrow. These things take time. Any potential release can only happen once the port is finished.
But dang, it looks quite sexy, huh? :-)
