TDO had nothing to do with this refit aside from booking the travel for WDI to meet with Design in Warren and the Suits in Detroit. This refit is 100% GM pushed. If it were left to TDO you likely would not have seen a refit until the next major refit of Epcot which could be anybody's guess if or when that would even happen.
It will be more than screens and projectors, it will be lighting, set and show pieces, new music and some really incredible tech that has been developed by GM specifically for this attraction. This one is being done right, and should set the benchmark for how these things should be done going forward.
