The 2018 LEAF is spec'ed to have V2G, but where are the solutions. I think the new 2018 LEAF is largely dead on arrival compared to the competition. A real V2G solution would be a reason to buy a LEAF.

Nissan would have to find a way to age the battery warranty according to V2G usage so that someone doesn't wear out their battery with very few miles traveled.

Based on this study's findings, V2G is a great way to wreck your EV battery:

Any use of V2G would have to compensate the EV owner, which the utility would gladly do.

While production rates are generally 4-6 cents per kWh, peak power production rates are much much higher. If V2G could prevent a utility from having to fire up an old coal or diesel unit for 2 hours a day that would be a big cost savings.

If you "sold" 40kWh of juice from your battery to the utility for $.06/kWh 250 days/year you would make $600 per year. Doesn't sound awesome, but might make up for the capacity loss.

Worth noting that this study was done in Hawaii, which is pretty tough on the Leaf. Also worth noting that electricity rates are insanely high, so V2G would probably still be economical even if the utility had to buy you a new battery every 5 years.
