I ran across some rendering of the new full-size Transit van. This is the Euro version however. Rumor is US version is reported to get a more F150-ish grill (which I don't think is really a bad thing). Body lines look decent I think. They make it look almost compact, when in reality its more in line with the larger Sprinters size-wise.
The EcoBoost 3.5L and the diesel a plus.
That said.... I don't think it will be replacing the E-series for full trail-ready 4x4 conversions
