Welcome to the wikia, ArcEarth.

I haven't seen any ecology videos either, which is disappointing... On the flip side, I'm impressed by the in-game intro videos. At least they really improved those.

As for Deviljho... yes, you can mount him. I saw one video where that happened. Not sure about new weapons or moves.
