Man I've been thinking HARD about this board too doc (well the MO8). Anyway....I was the GMWA last week and seen someone with the MO8....and MAN the piano was on point just like the one on the Motif. Dude says the only difference between the MO and the ES is......the MO has two less sound banks, and no sampler. He says the two missing sound banks aren't really noticeable as far as "church" sounds go. You know.....the pianos, electric pianos, strings, organs and brass (which he did admit were a little weak compared to fantoms/korg trs and extremes)! I've actually heard people on LGM state that, had the MO series been out 3-4 years ago, they would have never even brought an ES. So since this thing will work perfect for me in a live setup as well as studio (it has a sequencer), I am definitely considering it! Guess what I need to do now, is actually play one!
