Usually when GM says "Stay tuned" it means something's at least being considered, if not already in the pipeline.
Like all the answers to the 8-speed transmission questions. "Well our 6 speed transmissions are specifically engineered to work well with our new trucks, but we're always looking at ways to further enhance our powertrains, so stay tuned."
Pfft I know you have an 8 speed in the works for trucks as we speak.
