General Motors (as of May 2009)

Pontiac, known for it's iconic red arrowhead logo, the split grille design, and perhaps an overuse of random chrome accents, has been officially declared dead. They will not be producing 2010 Pontiac models. The writing was on the wall when they renamed the Grand Am the G6, and then shut down Grand Prix, GTO, and Bonneville and replaced all 3 of those with the G8.

The goal is to sell off or shut down Saab, Saturn, and Hummer.
The focus will be put on Chevrolet, Buick, Cadillac, and GMC; for the time being.
The ultimate goal will be to sell Buick or somehow incorporate it into the Cadillac brand.
GMC will be merged together with Chevy trucks.
This will leave GM with two core brands in the U.S. :
Chevrolet and Cadillac.

Not a bad plan, but it's going to cost millions of dollars to implement it, and it's going to take a bit of time and skilled planning.
Neither of which GM has a whole lot of left these days.

We'll see what happens I guess.
