All I can say is that I also have no interest in this piece, much less the series. Series-wise, the changes shown in the demo did not bode so well for me despite it having a great story. And the figure... All I will say is that if I wanted a combiner that was reproduced by Hasbro, I would easily choose Piranacon over this piece. However, I am completely fine with my Predaking.
However, those who have some level of fandom towards this combiner should overlook the colors. Chances are that the bigger fans will have purchased the SDCC variant and will obtain this one as well. And there is no evidence that Takara Tomy will reproduce the SDCC version at all (even though they are going to be working on the current Generations line).
So all I can say is that if you are collecting the line, and/or a fan of the character... Buy it. He may not be the most ideal version, but he is one that does deserve a chance to be part of a collection. That is, if not have a chance to prove its worth in the long run. Even if I, myself, am not buying it. I already have Predaking, and have a long list of other pieces that I hope to obtain. But in the end, I hope to see him in more than one collection shown by the members here.
