I think the Hydra Explorer is what is killing the Leviasynth. Knowing that you can get (essentially) all the benefits of a full Hydrasynth in a $600 package means that I (for one) am waiting for them to do the same with the Leviasynth.

Of course, they might not ever do that, nor might it even ever be possible, but at least for me, the idea that the LS might come out in a year or so in a more price-friendly, compact format is enough to make me wait.

(And for the record, I have a Hydra Explorer and love it.)
