This is good news. I mean, as fast as Transformers was built, it really would be close to impossible to keep up construction rates that quickly for five to ten years. Transformers is a clone at the end of the day, and since most of it is 3-D screens with the projections already developed, obviously not every ride was going to be made that quickly unless quality was going to suffer. Two years to build a brand new attraction with much more detail sounds a lot more reasonable, and I dont mind waiting another year for it to be done right. I would much rather have fully-developed rides and wait for them rather than more of the same (riders in trouble, evacuate, grab 3-D glasses) every year.
This is assuming, of course, that there actually is a better show in the works, and thats not just a clever spin on "we're running into delays".
