We'll unless Hyperion are the only developers left, I think you don't need to worry about the OS itself.
OS4 is a sure thing as far as I'm concerned.
I'd be willing to develop this for AMiGA, but I don't have an amiga atm (A1 preordered with KDH, coupon bought, etc).
So really, this is all good and no need for any rude stuff as you put it :-P
