They tried a "different" fanbase. They dumbed down Tierkreis, while not a bad game by any means, it pales in depth compared to the main series (IV notwithstanding). And you can see the results.
I can't say what Konami will do, but if they're hiring Murayama, it's a step in the right direction. It won't be marketed to another audience, it'll follow the line of the main seires. Which is what I, at least, want. And it's what ensures the most the quality of the game.
So with Murayama, you'll still have a very niche title that no one will buy but that will most likely be a masterpiece
