Well this certainly was a surprise this morning. The game will be released January 26.
Also, I find it interesting how a part of the trailer focused a bit on Celebi. Could they be re-instating the original GS Ball event from the original game?
EDIT: This page here: https://www.nintendo...tal-version-3ds has the following bullet point
- Get the chance to encounter the Mythical Pokémon Celebi in an event after completing the main adventure.
