Quoted from 3rdaxis:Unless there is some sort of iPhone app tied into the game so you can surf on Facebook at the same time to generate interest of the masses (or Apple zombie's lol) i think pinball is "peaking" or at least stable for awhile.
Pinball arcade is imo the reason you have seen prices move so quickly over the last few months. Millions of downloads on iOS and Android is getting people into buying, to relieve the old day.
