Since it's been brought up a few times: the last instance of pre release testing on location of a new game appears to have been Spider-Man in 2007. http://www.pinballnews.com/games/spiderman/index2.html At least, that was the last time I recall seeing pictures of a test game with red plastics on location before such title was officially announced. I do recall stories of games being tested on location later on as well, after being released, but apparently, nothing was done with the data collected (to much frustration of some of the people involved).
