I seem to recall Robert starting a thread about the auditorium and a revision coming a few weeks back. Doubtful that one is being discontinued but a revision/update may be in order eventually.
I was waiting to chime in. Generally the sale boards seem to be older ones getting an update. Might not always be the case but that's what I have seen.
I took feel pressured to buy every last sale board.
If it does stay unavailable for too long there are other testing units out there. My auditorium is my primary rig but if I get no signal I swap it over to a fuzzdog ultra tester as it includes a signal generator and audio probe on a switch.
