The top-end keyboards have been out of stock for a week or so, so at least we haven't been missing out on that opportunity (if you squint at it from the right angle). Mind you, they only show the "out of stock" message when you actually try to buy them. And yeah, it was definitely a pricing error.

Only the S keyboards, and only because they are getting ready to introduce the new models. A series and M series are still available (not as attractive, of course).

It's a pricing error. There is no way they will be able or willing to honor the hardware purchases. Software is good though, stock up on u-he products or Komplete updates!
