Fuel Cell Cars Will Make Hybrids Obsolete, GM Says. I really doubt if Larry Burns said anything like that. He is very smart and I am sure that he must have mean't that GASOLINE-hybrids will become obsolete. That may be true in about 50 years. However, hybrids as a technology is likely to be used even in fuel cell cars.
Now if Larry Burns really said that, then I feel sorry for him and General Motors. It may be case of sour grapes with Hybrids for GM!

Quick Update: I was sure that Larry Burns would not be irresponsible to make a statement like the one above. He really said that "Gasoline-Hybrids" will become obsolete. See the Automotive News Report.
