PKI has never had a B&M or Intamin coaster, but PKI has had a great relationship with Arrow. Also, PKI like record breaking rides and new and innovative rides. Who's to say that PKI will not stick with going B&M and Intamin free by going with an Arrow 4th Dimensional coaster? For all of you who say that the 4D is unreliable, well that really isn't the case anymore since Arrow has been working out all of the flaws. They even have a launching version of the 4D. Now if they could do that thne they could get the regular 4D worked out. Do you think PKI will see a 4D in the future?
