Well, call me a sucker, I'm going to order two more ceiling m3's. I spent the evening sizing up my ceiling and if I am going to dive into this Atmos thing, I'd rather go for four now and be done. I guess I will be one of the first few with Ceiling M3's for atmos.
I gotta feeling it'll be years before we see regular Atmos content but from what people are telling me the upmixer for Atmos is really impressive.
