I can't get through at all now to Casio on my usual contact phone #. I called my GC where I shop and told the manager the situation. He telephoned a Casio rep (?) and got back to me with the following info: Yes, Casio has delayed the release of the WK7500 until March/2011.

This is the strangest company I've ever dealt with. I'd be a little nervous now about buying one of their keyboards. I can envision the horror of having to have warranty work done on it and not being able to reach someone there.

I'm going back to considering the Ketron.
