Just spoke to them. They said the reason for it being delayed is because they are finalising additional features such as more facilities and bigger units. Apparently they received a lot of feedback that their biggest unit i.e. 1200 sq ft isnt big enough, so they are working on that. I suppose that would change the design/concept of the project.

As for the intended launch, the person said most likely end of 2016, which will push completion date to late 2020. Sigh...
