There was a rumor elsewhere that DVC will start converting rooms in the "resort" sections of some of the regular Disney resorts to DVC, starting with Wilderness Lodge.
My suspicion is that, at some point, one of the AoA suites will become DVC. It won't be as high of a point value as a 2BR in other DVC resorts, probably more like a 1BR because they only sleep up to 6 (versus 8 or 9) and the resort itself has far fewer amenities. Were that to not happen, I think they're going to float the idea of a "Value" DVC concept, a resort where rooms will be smaller (with perhaps fewer or no suites) with kitchenettes and fewer onsite amenities, but the point values will be much lower than studios anywhere else. It'll still have an over-the-top theme and look fun with a great pool, but it'll only have a food court versus a proper restaurant, simpler lounges with limited drink options, no gym or other things to do like bike/boat rentals. Perhaps not even a Community Hall (unless they're mandatory, as I've never seen a timeshare without one). It will, however, have a but-kicking general store, because there's no way the food court will be able to handle the amount of guests so more people will opt to do more dining in their rooms, even with the limited options of a kitchenette.
It'll be the DVC for park commandos who only want to hit parks until they're too tired to stand, and/or the members who want to extend their vacation a few extra days, and "slumming" it in the smaller rooms before or after a week in one of the Deluxe DVC resorts might add an extra day or two to their trip.
And don't forget, there's always the chance of more out-of-WDW DVC options, like Hilton Head/Aulani/Vero Beach, or options within other Disney parks like DL or DLP. Also, there's still Yacht Club.
I think there is a ton of growth left for DVC at WDW. I agree with the above about a more "value" based DVC line. I would buy into POR in a second myself
