I don't care how advanced a workstation or arranger keyboard is the simple fact that the Wersi, Mediastation, Oasys, and NEKO's price point is where its at will always limit their sales potential. This is true with any product developed for a niche market. Few people require the features these workstations and arrangers have to offer and for those of us that do, price is generally not of great concern.

If Wersi or Lionstracs built an arranger with sampling, synthesis, VST support, sequencing, hard disk recording, vocal harmonizer, and 76 keys that only weighed 30-40 pounds but the cost was $5,000.00 or more, few people would buy it. Case in point is the Wersi Ikarus which has all of these features and yet relatively few people own one. Price point is a major concern and no matter how hard a manufacturer tries, they can't build something of great quality on the cheap.

Even if Wersi or Lionstracs had a stronger presence in the US market sales would not "sky rocket". After selling high end pro audio gear for over 25 years... I've yet to ever see any single product that costs more than $5K be a runaway hit selling thousands of units let alone tens of thousands.
