I think the fellow is trying to generate pre-release hype/interest. Firstly, I am surprised that he is quoting a price, and secondly, he is using the always controversial and supposedly "unauthorized pictures".

4550 Euros= $5800 US [ who would spend that amount of money on a Tyros II??] That can't be right!! If it is they can promote all they want because they won't sell many.
