It won't be DVC. The way DVC operates, they don't let a property that is years away from opening take sales way from the newer ones that are still trying to sell out.
Hell, I don't expect Caribbean Beach DVC to be announced until at least next summer so as to give Wilderness Lodge some time to shine on it's own. Basically, they wouldn't announce a Epcot DVC this year when it won't open until 2020/2021 because they don't want people waiting for a specific property to buy in.
