It is true.It is my understanding that, in Black 2 and White 2 breeding, if a parent holds an Everstone there is now a 100% chance of the offspring inheriting the Nature of that parent, and that there is a high likelyhood that the offspring will also inherit the mother's Ability.
Is this true? If it is, how do you tell which frame you hit in RNG Reporter before picking up the Egg? Is there any possibility that RNG Reporter could be adapted to show the three stats a hatched Pokemon has that were not inherited from the parents? That would help things a lot, I think.

However, there's something wrong with the Egg RNG mechanics, so it currently impossible to RNG eggs.
