new dodge 1/2 ton diesel

I just read that Dodge is going to produce a 1/2 ton diesel pick-up this fall ( 2013 ) as a 2014 model, It will have a V-6 eco diesel. I'm not sure why anyone would want a diesel in a 1/2 ton truck, except maybe the fuel milage will be better, but with the price of diesel fuel, whats the point? I think I'd rather stick with my Hemi ram.
