Wasn't it sort of confirmed that we'll eventually be able to talk to pokemon. In B2/W2 he battle companies presidents grandson says that he is working on a way to understand pokemon.
Just like at some point there was girl who wanted a pink pokemon with flowers and just how at one point there was a person who wanted to see the dreams of pokemon.
I've notice a pattern that gamefreak usually do. When something usually get mention by an npc in an older game, it's a sign that it'll be implanted in future games. The biggest example is the Munna line. The translator didn't make in because of lack of time. Think of all the text that will need to be done. We'll either see this feature in X & Y 2 or gen 7, all i can say is that I welcome such a feature.
