CyGames have released the following statement:
After our first online beta was held in July, the development team pulled out all the stops to rework the game’s mechanics and battle design in time for the initially scheduled release date. Despite our best efforts, however, it has become clear to me that additional time will be needed to put the finishing touches on the game.
Upon completing our adjustments to the game’s battle mechanics, we revealed the changes during our Balance and System Adjustments stream on October 20 and the first public playtest at the “GBVS Official Tournament, vol. 7” last weekend, where they were met with an overwhelmingly positive reception.
However, due to the number of modes that were affected by these changes, we found the overall impact to be much larger than anticipated, and decided that, in order to meet player expectations, we would need two more weeks of polish and debugging to put out a truly high-quality product. We regret announcing this as the second beta is just around the corner, but please rest assured that the beta schedule itself has not changed.CyGames via https://rising.granbluefantasy.jp/en/news/detail/?id=vjcwnsxpv
