We know there's something because the max Gids is 292 on the 2015 cars, which is slightly more than prior MY cars. We also know that 100% charging is not impacting the cars much either. Maybe they are just trying to see how the packs hold up and if they wind up being much less effected by degradation, they'll just free up capacity with a software update!
Fact is, we don't know how much capacity they'd be able to add in the same size as 2011 packs in 2015. It could be sizable. Once we start seeing 2015s with more significant degradation (maybe in a year or two?), we might be able to interpolate based on curve fitting techniques what the actual capacity of the pack is. Nissan probably doesn't want people to know if the 2015s have more capacity, because it could lead to people rushing to get a battery replacement (i.e. more headaches).
"100% charging" might not be 100% charging anymore, if this theory turns out to be true. That could be one reason why the degradation is lower.
