That would be amazing, but that will all depends on how well the movie performed.
Both the game AND an anime is one hell of a demand. Especially a 3rd Klonoa game.
We've already known of how it went with Ratchet and Klank, where they get their own movie. Even though the movie itself didn't perform too well financially, and critically, with a box office of $13 million, compared to the budget of $20 million, they were still able to get a new Ratchet and Klank game. Well, unless it actually attracted PEOPLE to anticipate for a new Ratchet and Klank game.
It's more if the movie itself will be able to gain enough attention to the public with marketing, but we'll know when it happens later. For financial gain, it can add to the budget for a Klonoa game and anime. I think, I don't really know much of that if it works.
If it's able to get an anime, that's great! If it's the game, well that would be really amazing. If both, then a miracle it happens to be!
Though... if the movie didn't perform well, but was able to get a mass following, then Klonoa game. If it performed financially well, then anime. If both, then I guess both.
It's just my thoughts, they're kind of all over the place
