iPod Touch Nano revealed on NYC transit site?

Here I am minding my own business and checking a train schedule when I see this oddly shaped iSomething. Is it just a rendering or does it in fact purport what the new yet unmentioned iPod touch Nano will look like? You be the judge.

What we can tell from the image:

• Size-wise it looks to be a cross of the current iPod touch and the iPod Nano. A little wider screen, not quite as tall.

• The internet looks pretty good on it, or at least, the MTA mobile website.
• We could see this being somewhat interesting: very portable, very nice and wide screen.
• Still just one button, if it aint broke why fix it?
