GADV's been getting the shaft on additions for years so the rest of the chain could catch up to what we already had. We added 8 world class rides between 1995 and 2006. Now that everyone else has gotten Wingriders, launchers, and new woodies, it should finally be our turn for a big one (or big ones).
I will say that I'll be disappointed if Cedar Point announces a Dive Machine. They really are an awesome ride experience that we dropped the ball on adding numerous times if they get it first.
2011 was our last "major" coaster and even that was a relocation. It sucks that when I want to ride something new and exciting, I have to drive to Hershey or Busch Gardens as they are constantly investing in high quality thrills.
