100 have been declared already. The remainder will be added as sales reach the number of points those 100 studio represent.
The reason that I suggest VGF resort studios as having the greatest chance is because they have not sold all of points represented by those 100 units. Members who do not own at VGF can book them starting 5/13. Unlike Poly, which is booked up for Columbus Day weekend, VGF will most likely have rooms available to book on 5/13 without needing a wait list.
