Well, the same site lists the MR-1 at GBP305 GBP, which is equivalent to USD469. We can purchase the MR-1 in USA for USD350, sometimes less. That's about 25% cheaper than the store in England. Reducing the MR-2's quoted price of 548 GBP by 25%, the price of the MR-2 in USA becomes USD632.
Looking at the problem another way, Korg products like the MR-1000 are discounted by about 33% in USA. If Korg sets the MSRP of the MR-2 at $899,
then the USA street price will settle in at $600 a few weeks after the product is released.
