My cynical side firmly believes that pool hopping for DVC exists for one reason only.....to help sell new points!! It just sounds cool when a sales person can talk about the "exclusive" DVC perks...and for us who are jazzed about WDW anyway, anything that even hints at having an inside track on anything would be a nice selling point.
So IMHO, pool hopping will be around as long as Disney thinks it helps sell new points. As many have pointed out, it's a perk that a very small percentage of DVCers even take advantage of anyway, so it's clearly not stressing the system now that SAB is off limits.
