I hope it's abandoned. After all the hype and waiting it would have been unfairly and harshly judged. might aswell make a new and fresh idea.

It's probably not, they made it very clear last year it was actually being made and well focused now.
Also, 10 years of resources, work and waiting by our part, wouldn't be a good idea to throw it out, only if they really, REALLY, can't achieve what they want there with the game (in vision and quality), so they refuse to release it.

For all we know they haven't put any resources into it for 6 years now.  They may have started over.
