Wow, I was not expecting this. I agree with many of you about the whole licensing thing... but this is definitely way better than a Ghostbusters theme. I really enjoy the How to Train Your Dragon films and show, so, admittedly, I am excited for this as well.
Wasn't the series cancelled though?
It's 2 movies plus the series, right? (4 seasons)
Maybe I should have another go at it...
Yes, there are two movies. The first one was released in 2010, and the second one was released in 2014. The third one, as mentioned by others, is currently scheduled to be released in 2018.
The show has four seasons, and I haven't read anywhere that it's been cancelled. Unfortunately, similarly to Super 4, since it's been on Netflix from the third season on, there aren't any DVD releases of the show available after the second season. Netflix splits up their seasons into halves and for some reason calls them different seasons; there have actually been three full seasons and half of the fourth season released so far, but Netflix considers their three half seasons to be season 3, 4, and 5. I don't think that the show is as good as the films - due to lower quality animation and storylines that are less focused on character development - but it is still very enjoyable.
Another interesting thing to note is the age of the characters in the films and show. In the first film, the main characters are about 15 years old. In the second film, five years have passed, and the main characters are about 20 years old. In the show, which entirely (so far) takes place between the first and second films, the characters are at ages between 15 and 20 years old. The reason I mentioned this is that I am hoping the figures and parts will fit in with the existing Playmobil figures. They shouldn't be child figures, and hopefully they won't be Super 4 teenage style figures either, at least if the sets are designed with the second or third movie in mind.
