Saw it on this blog by Daegeun Lee. You know. The guy that accidentally leaked the Polaris launch NDA release date.
올 한해 가장 뜨거운 감자, 폴라리스와 Zen : 라데온 HD 4800의 영광 재현하려는 AMD

Just a rumor. Take it as you will what this means for what the next GPU release is for Apple.

In other words, even if the next MacBook Pro and iMac equipped with Polaris appeared as no surprise.

I think it's a good move on their part personally.
