Not sure what Aaron was smoking, but we've already had 2 revisits of Beast Wars by Hasbro - the 10th Anniversary set of 6, and the Universe set of 2.

Both seemed to be succesful enough to warrant more, or at least had enough sales statistics for them to investigate it further.
Implying that it was a surprise to him that there was fan/consumer support for Beast Wars is a bit disappointing, because it suggests his interests lie with Gen1 (what he grew up with) and Armada onwards (what he designed) - leaving a big Beast Era gap that he seems to have no interest in. If he's one of the people deciding the direction of TFs, we will only have him focussing on the eras he cares about, and put a half-assed effort into the Beast Era, that he seems to have ignored, both during its release and 2 subsequent revisits.
