I did not say that they had plans for Pokémon Z. And I was intending a sequel, not something like Pokémon Crystal or Emerald, but something like B2W2: a real sequel for the story, where the plot could be focused on Zygarde and its new forms. Zygarde is the legendary who protects Kalos and its environment, who rules Xerneas and Yveltal, why they have to push it in the next generation? And yes, they made a mess: it's clear that these (awesome) forms were created later, after they created Zygarde 50% and its ability... It's not logic to present a Pokémon in a middle stage, with an ability that's totally unrelated with those new forms and with Zygarde 10%'s ability. I'd really like to see how they will make Zygarde 50% transform into its Perfect Form!
