It is a fact that the game has been released. But unless you can provide any sales numbers - ACTUAL numbers, not guesses, all we know is the game has been released and ranked pretty low at Amazon's list of games selling.
Also, it was not on any pre-order charts on VGChartz before the Zumba game came out. They get numbers from Best Buy, gamestop and other brick-and-mortar stores.
Cash vault is refilling quickly, if the only info reference you have is VG sales then you should stay away from video game manufacturers. The news of several states to allow online gambling is nothing new. Revenue and taxes. That sector is about to explode. Great timing. Zumba on fire and bundled.
