No offense, my man, but this sounds like concentrated Copium. Let's assume you're right and this magical team of people has been working on this new content that isn't just a bunch of animations...How come they haven't added even a single quest to showcase their quest system? How come they haven't showcased a trailer or a gameplay video of whatever it is they were making?
There is no conceivable chance on this entire galaxy that a 'studio' wouldn't produce some sort of promo trailer to showcase what they were working on in order to garner even more support via crowdfunding.
Screenshots of store-bought unity landscapes with Maya slapped on top don't exactly impress me, unfortunately. If they legit have nothing worth presenting in its current state then they've been doing fuck-all this entire time, and I do not believe for one moment that they're keeping it a secret cause that would make them a bunch of morons.
Overall, I don't believe they're working on anything besides animations and other sandbox tools to milk modders dry who will, in turn, bring around a number of players as well as patrons in order to be milked dry as well. They're running it in what can only be called 'Maintenance Mode' where they do the bare minimum in order to keep the money flowing.
I could be wrong, mind you, but I highly doubt it and I highly doubt the integrity of the devs.
