Most of the Pontiac workers are now working on other vehicles mostly in the Buick lineup and you can clearly see that in the 2012 Regal GS. All you have to do is look at the interior to see that its "Pontiac" inspired.
I used to think, there's no way the Pontiac brand would ever come back, until yesterday on the news they were talking about how the Japan situation is going to affect those auto makers over there. If they fail because of the earthquake/ tsunami and GM becomes #1 or 2 in the world again, I could see them considering a return of the Pontiac brand, but that's the only way.
