When Natami is out, ppl will develope for its 3D features - is it compatible with other OS3 systems ? no if they dont have Natami - or more specifically if they dont have the SuperAGA chipset then they cannot use the 3D functions of the Natami.
I dont think anyone really gives a rats behind about the superaga + 3d capabilities of the natami. all people really want is new hardware to run old software. aka minimig + aga and faster cpu core + sdram.
imo the 3d + superaga is a lot of wasted developmental effort.
