AmigaOS 4.1.6 has been released more than a year ago. And OS4 has Sam460ex support and a 2D driver for Radeon R700 for 3 years.

Has there anything in particular been announced for this?

> Will it mean just 4000/4200HD model, or some wider varity based on same chips?

As you know, "R700 support" was the statement that was reportedly given on the Pianeta Amiga show last year. AFAIK, there is no HD4000 model, and HD42x0 models are R600-based. So I guess it should be HD43x0 models and above, but I have no inside knowledge whatsoever, only what has been stated in public for everybody to read upon.

> please no won`t work ...

The MorphOS Team made it pretty clear that there will be no Rave3D for R300 and up, so no Goa3D (which relies on Rave3D) either. But as soon as Wazp3D will run hardware-accelerated via TinyGL, you won't need Goa3D anyway.

It's been explained there by a MorphOS Team member:
