Surely a fanatical collector would buy a minimum one of each edition, then multiples if possible.

Not with the LEs. BUT - A loophole would be to order an LE from different distributors 

As soon as my LE hits the showroom floor, there will be at least 4-5 KISS collectors who will have the opportunity to play the game and then decide if they want a Premium or not. I had a customer play TWD LE today, and he walked away totally impressed with the gameplay. He is a KISS fan, and he wants the call the day I set mine up. I think once the scramble for the LE's is done - mostly KISS Collectors anyway - then Pinball fans will snap up the premiums IF the game is a good player will good code.
