I believe a transformation for Bizarro is in the works. Either 2015 or 2016 is my guess.
Also all that has been said about Goliath is true. The new trains are awful and I seriously can't think of a ride that I have been on that was rougher. The only enjoyable parts are the spikes, the rest is torture. I would rather ride Mind Eraser, Flashback, and Wildcat without track work than Goliath. It has gone from my second favorite ride there to absolutely atrocious.
