It's not coming for a long while and IMO probably never will, Amiga Inc tried to make a quick buck by insisting that only 'licensed' boards can run OS4, this basically amounts to slapping an extra chip on a completely ordinary PPC board that the OS checks for, the chip contains no information other than this 'license' so it's not like the ROMs for the old AOS.
None of this licensed hardware is being produced because AInc got into a squabble with the hardware supplier (Eyetech who sourced their boards from Mai) and threw their toy out of the pram, i.e. no new A1 boards are being made.
Other companies have come up with hardware (ACK's Powervixxen and Elbox's Shark spring to mind) but they wont release until OS4 is finished. Hyperion (the guys developing the OS) wont release until hardware is available.
So we're stuck with a chicken-and-egg situation and all AInc do is threaten people on ebay for legally selling old Amiga merchandise.
