The thing is, Rikki... Once the entire arranger is based about these loops, to a FAR greater extent than the SD-1 is, you are going to need more and more of them. Otherwise, you are stuck with what it comes with AND NO MORE. When a live loop guitar part sounds that good (and the demos bear this out), are you going to be happy with the remainder of your styles sounding inferior?
And at the price these come at, I see few changing to each new model, just to get a few more styles. But you are starting to realize what a PITA it is to create new content at the ROM standards. So the Audya better come chock a block with incredible styles, because it certainly doesn't look like Ketron are going to be adding much themselves, at least from prior experience.
They have already said the loops are going to come in from a HD, so the old ROM limitations don't apply, but ROM or HD, it won't matter a bit if what you get on purchase day is what you'll have on selling day...
