The WK3000 and the WK3500 have the MZ technology, so the sounds will be of this caliber but with 76 keys, smart media slots and on the 3500 you also get a disk drive these keyboards should do well at a street price between $300.00 and $400.00 dolars. Although they are not the MZ2000 replacements, they represent a huge bang for the buck advancement for Casio. I've seen pictures and I have a brochure in my store for a couple of months now. I'm amazed they can give you so much for so little.
