On the subject of future GTO models:
Just found out something:

Note the text:
Weakening sales for GM's aging truck lineup, including its most profitable models, were a major reason why GM posted a $1.1 billion loss in the first quarter, its worst result since 1992.

News groups reported this is why they stopped with the new GTO platform and focused research towards a new truck.

Good move as I'd rather see the company grow. This will prove to be beneficial as this can turn into a "get'em while you can!" and GTO owners can laugh and point at the people who procrastinated. It will eventually come back.
