As far as I can tell, anyone willingly touching OS4 at this point takes a big risk. There is no way telling how this lawsuit will end in year/two and *if* Hyperion loses (even partially) you'll end up in a lot of trouble if you'll been bundling your HW with this OS.
No company in their right mind would touch OS4 as it is now. Unless Hyperion rolls over on this, which I doubt, AROS 4.x will be out before OS4 sees the light of day again. After the last appeal has been filed, regardless who wins the initial court case, OS4 will be rereleased many many years from now.
