GM sale numbers falling even with new pickup line

I can't find the article right now, but had read a week ago that the reason GM truck sales, even with redesign, are not what they hoped, is that Dodge and Ford, both ready for a redesign, are offering major discounts and offers that make the deal that much sweeter. If you are not hard core brand loyal, this is what happens.

I think the article was on TTAC (The Truth About Cars).
