This was my reaction as well. Add $10K in options and a unique paint color, give it a cool name, and sell it for an extra $40k, which happens to be around the price pick-ups are reselling for. Smart way to get customers to voluntarily pay above their reservation price.
I also imagine this may reduce the desirability of the Edition 1 if this is ends up being an even more exclusive and higher end version of the Hummer.
Wish GM would focus on ramping up production on the base models rather than worrying about special editions but can't really fault GM for seeing an opportunity to increase profit margin.
