Maybe a stupid question: Are there some rumors or facts about new models for PSR 3000 or DGX 50.

This is a good question. The PSR3000 came out after the Tyros. Does anyone know how long after the Tyros was released that the PSR3000 came out? This may give us a clue as to when the PSR3100 would be released.

Looks like the Tyros was introduced at the Summer NAMM 2002.
PSR3000 came out in January 2004. So the PSR3000 was out 1-1/2 years after the Tyros.
Therefore
If the Tyros2 is introduced in the summer 2005, then the PSR3100 would be introduced in the Winter of 2007.

It doesn't mean a thing..Repackage models can turn every six months,,,need proof look at the Casio WK series, or even the lower PSR line..
