I can’t really give a timeline for my Eco-System project because i am still in the midst of building the individual elements, So 2018 is probably too soon.
However, I think you will like this, My next project is an Attack Boar. The Attack Boar will hunt any Actor with the appropriate enemy tag when it gets hungry or angry.
The neat thing here is that Rodents will run from any Actor with the appropriate enemy tag. So by adding just a couple of tags the Rodents will run from the Attack Boar while the Attack Boar hunts them down. This behavior will work with the player as well. it’s already testing quite well 
Good things to look forward to, to be sure.
I haven’t been working with sequencer, so I am not sure- but my guess is it would take some custom adjustment on your part.
