Scott,
Just got home myself and I just have two things to add to your report. Korg did show a new arranger keyboard called the SP-500 (Retail Price $1800.00) which is a hammer weighted 88 key version of the i series keyboards. It features a touch screeen (from the i30) 32 note polyphony, 128 or 192 (can't quite remember) styles and over 600 sounds. It features the chip from the i40 keyboard and is made in Japan, not Italy. It was very nice for the price. Unfortunately, I just dropped all the literature and brochures off at my store on the way home which included all the specs on the new products. I bring these home Monday evening. I even got a CD rom from Generalmusic with all the data on their new Genesis.
Yamaha did have four new arranger keyboards including the DX500 with 88 keys and looks like a $3000.00 keyboard but in fact lists at $795.00 with a beautiful matching stand included. These were not pro arranger models so that might be what you were talking about.
