In answer to my question from August, "Is this the Nissan Cube I've been waiting for?" the answer is, "Yes, and they even flipped the rear asymmetry to accommodate LHD and Right Side of Road driving."
Nissan finally unveiled the 2010 Cube at the LA Auto Show. It's the third generation of the awesome little space car, and the first to come to the US. It's about as big as a 1st gen Scion xB, and it should help push the bloated 2nd gen xB over a sales cliff where it belongs.
In Japan, the Cube manages to have three rows of seating. In the US, we only get two, though the rear seat slides back to provide limo-like legroom. When I confirm you can fit three car seats across the rear bench, like in the xB, I'll update the post--and start clearing out the garage. [figuratively speaking, of course, since we don't have a garage.]
