In Japan they also release dvds while the season is still airing and the same may also be true for North America. So dvd releases are not a sign for the end of a season. and the document by viz media also mentions 52 30-minute episodes not 52 15-minute episodes. Also they announced 52 episodes from the beginning on. Thus season 1 will air in the US until september and after that probably be succeeded by second season.

P.S: Last week's episode was once again very successful with 934000 viewers only 1000 viewers less than Beywarriors which aired more than a hour later.
