Jalopnik, the site that had gotten some closeups of the mysterious Corvette spotted at Edwards Air Force Base during Transformers: Revenge of the Fallen filming, has it that it's not the potential design for a next-generation Corvette C7, but rather it's GM's Corvette Centennial Design Concept, according to their sources. Said vehicle is to celebrate GM's 100th birthday and more details may be revealed before Revenge of the Fallen comes out.
