This way, they could then focus more on just making fun animation without having to make sure the anime deadline follows in line with when the next game comes out because the anime is now in "perpetual filler" mode right now.
And in a perfect world, they could allow more time for game development as they no longer have to make sure the show is wrapping up in time with the next game release. If this series has to drag on a bit longer to compensate for more game development time, this format is more flexible for that.
