I'm a bit late to the game to reply to this...but I've been letting the redesign soak in a bit.
I know its an all new truck, but it looks like a re-skin to me. I don't necessarily mind it.
When Dodge went from Gen 1 to Gen 2...it was a MASSIVE redesign, and a real attention getter. I was 16 when the 1993 came out and boy, did I want one. Ford and Chevy couldn't touch those looks. When Gen 3 hit in 2001...I was "meh" about it (well...for all models except the SRT 10).
Gen 4 moved the Ram in the right direction (in my opinion). The '13 changes dialed it in even more. I really think that in the right trim, the strong simplicity of the current model will look good for years to come (I feel the 90's models have aged well too).
This new one? I'm not sure, I guess we'll have to see. I don't feel Dodge has ever done the "sleek" look all that well...I'll have to see one one the street to form a real opinion.
