New F150 coming to Detroit auto show

I actually love the look of the Atlas concept truck, which the new F150 is supposed to be based off of, so I can't wait to see the new model. I've actually delayed my planned truck purchase just to see what Ford comes up with. I read somewhere that Ford will be offering a smaller displacement Ecoboost with this truck, something like 2.7L, in order to help boost fuel economy, although I cannot confirm the validity of that. If that's true, I hope the 3.5L will still be an option for those who need to tow heavy.
