I'm not sure how that's even relevant.
By my calculations it would cost over $300,000
per day to give the
DDP "free" to
DVC members. That's taking every WDW two bedroom villa and assuming a reasonable occupancy level (which would probably rise if every guest ate for free) at the current DDP fees.
As you pointed out, there's a financial incentive to the free dining credits given to cash guests. I don't care who is in charge of DVC or what they are "all about." DVC didn't give out $10 million worth free meals per month before Jim Lewis came on board and they aren't about to start today.
BTW, I made my ADRs this morning and got my first choice of time at every restaurant.

So at least the Disney Visa people didn't have any impact on us. And I think there is hope that a general public announcement won't have an
immediate negative impact. I think people have come to expect the free dining promotions in August and September (one reason I'm surprised Disney kept it up so long) and are prepared to call as soon as its offered. How readily they will jump at the offer for Oct - Dec remains to be seen. Could be more of a slow burn.
