How many V2 systems are out there and if there is more than a handful, it would seem like this would be bigger news?
AFAIK, they're only in Japan. At the interview I pointed to at http://www.mynissanleaf.com/viewtopic.php?p=504949#p504949, there are supposedly 7,000 such setups in Japan.
However, I have no idea what forums Japanese Leafers tend to hang out on but they're likely primarily in Japanese, which I can't read. And, in the Leaf FB groups I'm on, it's not like folks pre-announce that they have a V2H system and are down x capacity bars. And, there's an incredible about of CHAdeMO over there (https://www.chademo.com/ says 7400 stations in Japan) along w/lower highways speed limits, so range on a single charge is likely less important.
And (I don't know the details, someone will have to fill in the gaps), apparently, there's virtually no demand for used cars there (talked to a guy from college who lived in Japan for awhile and did have a used BMW 8-series there). https://www.nytimes.com/1993/09/12/world/why-the-cars-in-japan-look-just-like-new.html from 1993 talks about the inspection system and
In the United States, 64.1 percent of passenger cars in 1991 were at least five years old. In Japan, only 46.8 percent were. In the United States, 30.5 percent of cars were at least 10 years old, versus 9.6 percent in Japan.
With little demand for used cars, cars here lose their value quickly. "A car more than six years old and in very good condition you can easily see in a junkyard," said Hiroshige Hanabusa, who makes a living helping people with the administrative chores associated with their cars.
Many of the used cars find their way to other nations, where they are considered bargains. In New Zealand, used Japanese cars are cutting so heavily into sales of new cars that auto dealers and assemblers have complained to the Government. And Russians can't get enough of old Japanese cars. Taking Cars Home to Moscow

no demand for used cars in japan years.

I have no idea how accurate these are regarding "shaken" over there:

So, the above factors also might skew how long Japanese Leafers keep their cars vs. those in the US.
I'm still at 11 bars on my 5/2013 built used Leaf past 62K miles w/SOH now hovering around 82.xx to 83.xx%. As a reminder, at http://www.mynissanleaf.com/viewtopic.php?p=496269#p496269, I pointed to a Phoenician w/the same build month as me who lost his 4th bar on 8/23/16 at 31.4K miles.
