The person who posted the thread about an upcoming PSR4000 and PSR2500 in July responded to queries.

He said that he got his information from a friend who works in a music shop in Jakarta, and that he is certain that his friend is not lying. He said that his friend told him that he would have more information in May.

The PSR3000 and PSR1500 are made in Indonesia. It is plausible that someone working in musical instrument sales in Indonesia might get some leaked information. We'll see.

I would be surprised if Yamaha brought out a new model.
