I'm sure they'd port OS4 to other, similar, hardware.
Makes sense. I mean, really, an AmigaOne was really only just a 3rd party board that AI (or now KMOS?) gave it's blessing to. If MAI folded (still unknown) all that would need to be done is for a new board to be chosen, some small business deal hammered out, and Hyperion to write drivers for it.
Doesn't seem like the end of the world. Certainly not great news, but nowhere near the worst news that has befallen Amiga. It's my hope that they'll find a board that is a little more competative and up-to-date, and a little less quirky and obscure. (Hey a guy can dream, right?)
