It doesn't matter to me how many new features are added as long as Korg is continuing to support the PA2X Pro, I commend them. Chances are the updates won't be earth shattering but the PA2X Pro is already a fine musical instrument so any additions are welcomed additions.
Like the PA2X my Yamaha 9000 Pro was supposed to be future proof with software updates but Yamaha pulled the plug on it. 9000 Pro updates were more difficult to find than a cure for cancer would be before Yamaha discontinued it. After they discontinued it.... fugget about it! Just be glad Korg isn't orphaning the PA2X at this time.
