Isuzu WILL be gone by 2005, they're pulling out of all truck sales all over the world and will be sticking to commercial trucks (their cash cow).

Suzuki, Saab and Saturn will not die out. Of those three, the only possible one to die would be Saturn, which GM has full control of (it's a genuine GM nameplate). GM only has partial ownership of the rest of those brands listed, so they'll continue to supply money to them.
