Honda revealed two concepts at 2007 NAIAS, one is a general idea of what the next gen NSX will look like, the other is the next gen Accord Coupe. Keep in mind, these are not production versions, the production version of the Accord Coupe will be revealed at the Tokyo Motor Show this fall, i believe, not sure about the NSX though.
First up, is the "Acura Advanced Sports Car Concept"

For those who don't know much about it, this car will be powered by a V10 powerplant putting out at least 500 ponies, and will feature a rear wheel biased SH-AWD.
I personally think that this car looks awesome, it is more subtle and sleek then Lexus's LF-A, but it does so in a good way. Whereas the Lexus is elegant and smooth, this car seems like its about to pounce, it features powerful muscular lines. You can't lose when you are planning to pick a flasgship from the next gen japanese exotics, the LF-A is great, the NSX just as good if not better, the GT-R although loses out in looks but makes up in price. Here's a pic of the LF-A for reference, this is the latest incarnation.

And here is the Honda Accord Coupe Concept:

I personally think this will be the new benchmark. The new Altima Coupe does not even come close in style. The newly released Camry doesn't hold a candle. From Honda tradition, we can predict that the sedan will share a similiar front end, but the rear end will probaly be different; that is assuming that Honda carries out the same method that they used with the current gen accord.
With these two new products coming in the next two years or so, we can predict Honda Sales to increase.
