I think this car is going to turn out great (knock on wood). The seem to be trying to dupe us with the coverings. I have some opinions on a couple of things.
The taillights:
I doubt the taillights will extend into the trunk (it appears the reverse lights do, but then what are those next to the liscense plate?). Also, the look of the lights themselves seem to suggest LED. They seem like mainly a reflective surface and then two light areas (brakelight/taillight and turn signal).
The bodyline:
It appears the concept's body line could make it after all. While the reflective part of the taillights wrap around, the lit part does not. DOT standards mean taillights need to be seen from the side (hence side markers). This could also be why Acura isn't using the TSX's turnsignal-blinkers, as the turn signal will be in the body line. (I think this is a creative way to incorporate the lights, handles, and bodylines; however, I think there's better looking ways to do it than the concepts. Hopefully this will be better looking, because it just reminds be of an 80's for Econoline

)
The exhaust:
I personally think it looks good. I don't see this "Pontackiness" everyone is screaming about, I think it looks sporty. Also, if companys want to make aftermarket exhausts, can't they do so and have the tip in the shape of an upside down T?
The drivetrain:
Ok, so the big word as of late seems to be Acura's going to throw in HPT, a performance oriented version of VTM-4. In my mind, this is a very realistic rumor. Honda knows that Acura has fallen, and that while FWD won't survive in luxury, RWD isn't necessary. Now, everyone seems to be saying '270hp standard, 300+ in Type-S'. Now, there is no TSX Type-S, and apparently no upcoming TL Type-S, which would leave only the RSX Type-S. Now, if 270hp is standard, then does Acura feasibly need a Type-S model? That 10 more than the current Type-S. I think HPT 6-speed will be for the enthusiasts. I'm not saying Acura won't make a Type-S, just it seems they don't need to be in any rush to do so.
