The new CGP700 is an 88 weighted keyboard with a 40 watt speaker system and large Touch Screen interface. Here's what I know so far:
New improved drum sounds (finally!)
New styles
Audio Recording
comes with stand with 2 of the speakers in the stand and 2 in the keyboard so if you want to remove it from it's furniture like stand and take it on a gig there are still speakers in the keyboard and there are stereo outs as well
I haven't seen it yet but pictures and a demo will be on the Casio website tomorrow.
The MAP price will be $799.00
Shipping to dealers in August

Casio is also showing a new PX360 which will also feature the touch screen, be extremely portable and will now include the top of the line PX860's grand piano which features natural string resonance and other features found in Casio's PX5S stage piano.

I've liked the Casio Privia line a lot but I've always been disappointed with the user interface and lack of a numeric keypad or data wheel to navigate. Now with a touchscreen things should be looking bright for Casio's Privia line.

The new PX160 piano which we've received has now added better speakers and finally a lower priced digital piano with stereo outputs!
