Korg's reply to the Tyros 5 release?
(just joking...)
TBH, that's all any arranger needs to do to keep up with Yamaha!
Yamaha's development pace is so slow, and Korg's update pace is so good (Roland's as well), often your old gear is more capable than when you bought it, and has more styles. In the meantime, the only way any Yamaha user got better capabilities was to buy a whole new arranger.
Now, if only we could stop trading factory and 3rd party commercial styles like bubblegum cards, we might actually have enough USABLE new styles to make us think we had a new arranger every few months! Nobody's going to make them if they can't make a living from it!
