Sounds like they just want to delay tooling up. Or worse, they have not yet designed a replacement, which means they will be behind the curve as others bring to market more economical power. Keep in mind, every market analyst worth their salt is predicting fuel costs to raise and remain steady in 2010.
Glad to hear they will at least have a V8 option. I too like my american muscle; but the reality is Obama will dictate our choices as long as he is in power. Rising fuel costs will provide all the momentum he needs to push yet another of his big government solutions.
As for Ford; they have no plans to drop their V8's; the 4.6 is very close to the Northstar for power/weight/fuel consumption and they plug/play it wherever they can. But it too will need some tinkering or a newer version with improved fuel numbers if it is to remain as their mainstay.
