Great sales pitch.  I want to run out and buy it

I researched and decided I would stay with my Nikon D7000

Very tempting...

I tried to count the number of times he says, 'amazing', and I got lost. But I enjoyed his enthusiasm.

Note that he summarily dismisses Nikon's new mirrorless, interchangeable lens cameras, on the basis of their smaller sensor size. That's because he is a fully-professional photographer wanting maximum quality results under all possible shooting conditions. It makes perfect sense.

But mere camera enthusiasts like us can still reap benefits from Nikon 1 MILCs, based on their greater compactness and lower lens costs. (Costs are very roughly proportional to lens size, all other things equal.)

The body weights of the Sony A7S, Sony A6000 and Nikon 1 V3 are 1.18, 0.76 and 0.71 lbs, respectively, but more telling are the body volumes (WxHxD): 35.2, 21.2 and 14.9 cubic inches.

Relative lens sizes (volumes) and weights vary, simplistically, as the cubes of the inverse crop factors. These numbers are 1.00 (FX), 0.30 (DX) and 0.05 (CX), placing the Nikon 1 lens sizes and weights at 5% of the bigger Sony. Costs may not decrease in the same proportions, of course, for various reasons.

But convenience increases.

For example, my new 1 Nikkor 190-810mm-equivalent lens will fit in a large jacket pocket. Nikon's full-frame 800mm lens, for comparison, weighs over 10 lbs, is over 18 inches long (without hood), and costs about $18,000. My lens cost me $1,000 (5.5%) and its quality is essentially perfect. It weighs in at 1.2 lbs, roughly double the 5% mentioned above, but, Hey...

By the way, Sony does not (yet at least) offer an 800mm lens. Nor does Sony come close to the Nikon's 60pps burst mode; Sony has 11pps.

Low light ability is where Nikon's MILCs lag behind the larger cameras: The light-gathering abilities of the same-focal-length Sony A7S, Sony A6000 and 1 Nikkor lenses are, very approximately, the inverse squares of the sensor crop factors, these being 1.00, 0.44 and 0.14, respectively.

One needs to sacrifice something.
