There is no known schedule of the timed prizes. The order is also changed from Beta so which prizes will appear next is unknown.
One change that would be nice would be to allow for some type of add on bonus if you build the soccer field, 2 bleachers and 2 grandstands. It completes the picture and would perhaps make the thing more worth it.
