Here's what I think would make a cool, innovative wakeboard boat:
Take out the V-drive and put in a pod for efficiency, like that Mercruiser Zeus counter-rotating prop system. Then do dual rudders, like Epic, so that baby really turns.
Next, do a touch screen display, like Tige, only make the screen much larger so you can watch videos no matter where you are in the boat.
Finally, make it electric, zero emmisions. Use lithium batteries so the thing can go for like 10 hours on a charge. Then have a standard plug-in and/or an external diesel generator that can charge the whole system in an hour.
That would be sweet.
