I saw an interview with Bob Lutz (very high level GM exec.) recently about all kinds of things, mostly the current state and future of domestic auto manufacturers. He stated "we are not discontinuing production of any of the Lamda's". His words.
Honestly, why would they? Many people have the need for a larger vehicle like an SUV. The current future of this type of vehicle is a large crossover like the Lamda's. For once, GM is ahead of the curve instead of behind it.
