Most vettem észre, hogy válaszoltak a Kawaitól már 5 napja, csak a gmail kihajította valamiért a spam mappába, amit meg csak akkor vesz észre az ember, ha direktbe elkezd kutakodni a spam mappában.

Ezt írják:

First of all, thank you very much for your interest in KAWAI products.
At the same time I'd like apologize to you for the production delay at our factory.
Especially concerning ES7 series, we have the biggest supply problem
and we disclose that the delivery time might be around 3 months after order at this moment.

Finally we'll receive several units in the end of April.
Thank you very much for your kind understanding in advance.
