Mike,
Yes, all the other styles are on the WK6 Latino keyboard. What they've done is put the new Latino styles in the flash ram empty locations. There are 32 empty flash locations on the WK series and they've put either 16 or 24 Latino styles in these areas. They've also increased the flash rom from 2 MB to 8MB to have enough memory for all the additional Latino samples and loops.
I think this is the direction Generalmusic will elect to follow. This way they can have a keyboard for under $2000.00 that can be both "International" as well as "niche" specific. Genesis will be at least as expensive as the current WK8se if not a bit more. I don't know if these newly developed Latino collection style and sounds will be able to be used in Genesis but my guess is that they probably will be able to.
