Update: Clarification – PokeBall opening animations added in latest Pokemon X/Y update
Update: Serebii’s initial report was a bit incorrect. Here’s some clarification about the situation:
Following the release of the Version 1.3 patch last night, one of the small features that have been added has been confirmed. In addition to various bugfixes, such as a fix regarding Vivillon’s image not properly appearing in Friend Safari’s menus, the patch now fixes various special animations for when PokéBalls open on trying to capture a Pokémon or sending one in battle. Previously, these animations could be seen in battle, but not when you sent out your first Pokémon. Now, these will always appear when they are your first Pokémon sent in battle
Pokemon X/Y’s 1.3 update adds a small touch. PokeBalls open and display special animations when trying to capture a Pokemon or sending Pokemon into battle. Dream Balls and Cherish Balls had separate animations previously, though all except Apricorn Balls now appear to have new animations.
