I think Casio is testing the waters with this new offering.
Yes the specs look impressive for Casio but I would not classify it as a TOTL.
And how it sounds is going to play a big big part of the whole equation.
It would be interesting to see what the price is and how they market it.
I think this is meant to compete with the Yamaha S710.
But like Fran said it will not attract the S910 or prelude buyer.

What it does however is make the case for Yamaha to make a 76 key S series.
I am sure Yamaha is listening because this offering from Casio seeks to cut in to Yamaha’s very lucrative entry level arranger products.
How did they manage to make the 76 key version only 19 LBS?
