Chris Sawyer works with coaster designers (how the game is so good, those sorts of inside details) and I'm sure these ideas that appear "new" to the public aren't really knew to the designers. All ideas have to come from somewhere, and I'm sure they've been on the drawing board for awhile. They would just be adapted into the game.
