For reasons I don't understand SAGA was chosen for the name of the RTG graphics that come out of the HDMI interface. Gold 2.7 will still have that with ECS/OCS still coming out of the RGB port.
So nothing new, just at last an FPU of some sort.
So you have no information on whether it will fully implement all 68882 instructions and features on the FPGA, or whether it trap those that are not implemented and feed them to a software emulator, like is done with 68040 and 68060 using their respective libraries? There was such a hoopla over how utterly crap solution it was to need such libraries, yet from what I can see, they're doing the exact same thing themselves.
Gold 3 will introduce actual AGA support and the new Pamela sound chip over HDMI.
So Gold3 will introduce actual SAGA.
I guess there isn't any news after all then, just confusion and hyperbole (AMMX, AMMX2, AMMX2 + undocumented functions... which never seems to settle).
