By the time we left on Saturday all of the MK had been switched over. I believe they are switching them all as many days you were not to even put your ticket through the turnstile they were using handheld devices and/or stamps to indicate your use of the ticket. We were at AK one day and nothing tied to the computer system was working no fast passes and no tickets through the turnstyles--we stayed about two hours, but it got so crazy that we just left for a park that "worked". Many days no fingers were necessary at MGM or Epcot.
