Wow, looking at the comments on that autoblog site, I hope Nissan doesn't pay attention to them. Most of the comments appear to be from generation Y'ers, that have no concept of form-follows-function. It appears that Nissan took some styling cues from the 1950s Jeep FC vehicles; I wonder what those commenters would think of FC's?
No one knows how much the next generation Cube is going to look like the present one, but here are my guesses:
1. The asymetric rear window gets changed, either to a symetric one, or a "flipped" version for the US.
2. Bucket seats become an option or even standard.
3. The US gets the 1.8 L engine, fuel economy drops to 33 ish on the highway.
