Yes, sadly. I'm afraid that these formats were never fully supported by either record labels or retail outlets and are effectively dead in the water. At best, they represent a tiny minority of consumers (myself included) and we are poorly served.
I can't see any major manufacturer putting the facility into any BD player except at the top, top end.
My solution was to get a Pioneer SACD/DVD-V/DVD-A player and hook that up to the system. This gives me the upside of upscaled region 1 DVDs too. Not ideal, but a solution.
